delivered the opinion of the Court. ‡
The Presidential Election Campaign Fund Act (Fund Act), 26 U. S. C. §9001 et seq., offers the Presidential candidates of major political parties the option of receiving public financing for their general election campaigns. If a Presidential candidate elects public financing, § 9012(f) makes it a criminal offense for independent “political committees,” such as appellees National Conservative Political Action Committee (NCPAC) and Fund For A Conservative Majority (FCM), to expend more than $1,000 to further that candidate’s election. A three-judge District Court for the Eastern District of Pennsylvania, in companion lawsuits brought respectively by the Federal Election Commission (FEC) and by the Democratic Party of the United States and the Democratic Na*483tional Committee (DNC), held § 9012(f) unconstitutional on its face because it violated the First Amendment to the United States Constitution. These plaintiffs challenge that determination on this appeal, and the FEC also appeals from that part of the judgment holding that the Democratic Party and the DNC have standing under 26 U. S. C. § 9011(b)(1) to seek a declaratory judgment against appellees upholding the constitutionality of § 9012(f). We noted probable jurisdiction pursuant to the statutory appeal provision of § 9011(b)(2), which provides for a direct appeal to this Court from three-judge district courts convened in proceedings under § 9011(b)(1). 466 U. S. 935 (1984). We reverse the judgment of the District Court on the issue of the standing of the Democratic Party and the DNC, but affirm its judgment as to the constitutional validity of § 9012(f).
The present litigation began in May 1983 when the Democratic Party, the DNC, and Edward Mezvinsky, Chairman of the Pennsylvania Democratic State Committee, in his individual capacity as a citizen eligible to vote for President of the United States1 (collectively, the Democrats), filed suit against NCPAC and FCM (the PACs), who had announced their intention to spend large sums of money to help bring about the reelection of President Ronald Reagan in 1984. Their amended complaint sought a declaration that § 9012(f), which they believed would prohibit the PACs’ intended expenditures, was constitutional. The FEC intervened for the sole purpose of moving, along with the PACs, to dismiss the complaint for lack of standing.
In June 1983, the FEC brought a separate action against the same defendants seeking identical declaratory relief. It was referred to the same three-judge District Court, which consolidated the two cases for all purposes. The parties submitted 201 stipulations and three books of exhibits as *484the factual record. After extensive briefing and oral argument, the court issued a comprehensive opinion, holding that the Democrats had standing under § 9011(b)(1) and Art. Ill of the Constitution to seek the requested declaratory relief, but that the Democrats and the FEC were not entitled to a declaration that § 9012(f) is constitutional. 578 F. Supp. 797 (1983). The court held that § 9012(f) abridges First Amendment freedoms of speech and association, that it is substantially overbroad, and that it cannot permissibly be given a narrowing construction to cure the overbreadth. The court did not, however, declare § 9012(f) unconstitutional because the PACs had not filed a counterclaim requesting such a declaration.
I
In their respective suits, the Democrats and the FEC relied upon 26 U. S. C. § 9011(b) to confer standing on them and subject-matter jurisdiction on the three-judge District Court. Section 9011(b)(1) provides:
“The [FEC], the national committee of any political party, and individuals eligible to vote for President are authorized to institute such actions, including actions for declaratory judgment or injunctive relief, as may be appropriate to implement or con[s]true any provisions of [the Fund Act].”
Section 9011(b)(2) confers subject-matter jurisdiction on the district courts of the United States, sitting in panels of three judges in accordance with 28 U. S. C. §2284, to hear proceedings instituted under § 9011(b)(1).
We do not doubt, nor do any of the parties in these cases challenge, the standing of the FEC, which is specifically identified in § 9011(b)(1), to bring a declaratory action to test the constitutionality of a provision of the Fund Act. We think such an action is “appropriate” within the meaning of that section because a favorable declaration would materially advance the FEC’s ability to expedite its enforcement of the *485Fund Act against political committees such as NCPAC and FCM. This is especially important because the relatively short duration of the then upcoming general election campaigns for President allowed little time in which to prosecute an enforcement action before it would become moot in whole or in part. We are fortified in our conclusion by § 306(b)(1) of the Federal Election Campaign Act of 1971 (FECA), as added, 88 Stat. 1281, and amended, 2 U. S. C. §437c(b)(l), which provides that the FEC “shall have exclusive jurisdiction with respect to the civil enforcement” of the Fund Act. Article III standing exists by virtue of the facts that the FEC and the PACs have adverse interests, the PACs threatened, and now have made, substantial expenditures in apparent contravention of 26 U. S. C. § 9012(f), and the declaratory relief the FEC requests would aid its enforcement efforts against the PACs and others similarly situated.
Despite the identity of the relief requested by the FEC and the Democrats, the FEC asks this Court to reverse the District Court’s holding that the Democrats also have standing under § 9011(b)(1). The Democrats maintain that there is no need to resolve this question because there is no doubt about the standing of the FEC and the legal issues and relief requested are the same in the two cases. See McCulloch v. Sociedad Nacional de Marineros de Honduras, 372 U. S. 10, 16 (1963). The PACs have declined to renew or brief their jurisdictional challenge in this Court because in the present procedural posture they see the standing question as a “turf fight” in which they do not wish to participate.
Though McCulloch, supra, is authority on its somewhat different facts for finessing a decision as to questions of “jurisdiction” in one of two companion cases raising the same substantive issues, we decline to follow that course here. The statutory standing issue is squarely presented by the Democrats’ appeal, and if the FEC is correct in its assertion as to lack of standing, the decision of the District Court could seriously interfere with the agency’s exclusive jurisdiction to *486determine how and when to enforce the Act. In the present cases, for example, there is no indication that the FEC would have filed a complaint against the PACs for a declaratory judgment if the Democrats had not done so first. The FEC might have chosen to focus its resources elsewhere or to pursue an enforcement action at a later date. The Democrats forced its hand; the subject of the litigation was so central to the FEC’s function that it had no choice but to intervene once the action had been commenced.
The plain language of the Fund Act and the FEC A suggests quite emphatically that the Democrats do not have standing to bring a private action against another private party. In addition to the FEC, § 9011(b)(1) applies only to “the national committee of any political party” and to “individuals eligible to vote for President.” Clearly the Democratic Party is not included; hence the District Court erred in permitting it to remain in the proceedings. The DNC is a national committee of a political party, and Edward Mezvin-sky is an individual eligible to vote for President; therefore, they are authorized to bring actions under § 9011(b)(1). But such actions must be “appropriate to implement or construe” the provision of the Fund Act at issue. The District Court’s conclusion that the language of the statute “plainly” authorizes a private suit to seek construction of § 9012(f) seems to us to ignore the word “appropriate.” That word would be superfluous unless it restricts standing to suits which are “appropriate” in light of the statutory scheme for interpreting and enforcing the Act.
This scheme seems simple enough. Title 2 U. S. C. §437c(b)(l) provides that the FEC “shall administer, seek to obtain compliance with, and formulate policy with respect to” the Fund Act and confers on the FEC “exclusive jurisdiction with respect to the civil enforcement of” the Act. Title 26 U. S. C. § 9010(a) authorizes the FEC “to appear in and defend against any action filed under section 9011.” Reading these two provisions together with §9011, “appropriate” ac*487tions by private parties are actions that do not interfere with the FEC’s responsibilities for administering and enforcing the Act. Common sense indicates that only one body can intelligently formulate the policy necessary to administer an Act of this kind. The decision to sue third parties to construe or enforce the Act falls within these functions. Accordingly, private suits of this kind are inappropriate interference with the FEC’s responsibilities.
Consistent with this statutory scheme an “appropriate” role for private parties under § 9011(b)(1) would be to bring suits against the FEC to challenge its interpretations of various provisions of the Act. For example, the defendant PACs might have instituted an action challenging the FEC’s interpretation of § 9012(f) to cover the type of independent expenditures they planned to make. The specific authorization in the adjacent § 9010(a) for the FEC to appear in and defend actions under §9011 implies that Congress contemplated that private suits pursuant to the latter section would be directed at the FEC. Lest one ask why the FEC is also given standing under § 9011(b)(1), the obvious answer would be to give it the benefit of a three-judge district court and direct appeal to this Court under § 9011(b)(2), which procedures are not available in ordinary §437c(b)(l) enforcement actions. See 2 U. S. C. §§437g(a)(6), (10).
This interpretation makes a good deal of sense. Suits to construe the Fund Act and to bring about implementation of the Act — presumably implementation by the FEC, which has exclusive authority to administer and enforce the Act— raise issues that are likely to be of great importance and in Congress’ judgment justify a three-judge court, expedited review, and direct appeal to this Court. Ordinary enforcement actions to obtain compliance with the terms of the Act after they have been construed and implemented would not justify such extraordinary procedures. Moreover, it seems highly dubious that Congress intended every one of the millions of eligible voters in this country to have the power to *488invoke expedited review by a three-judge district court with direct appeal to this Court in actions brought by them against other private parties. The DNC is obviously not just another private litigant, and it would undoubtedly be a worthy representative of collective interests which would justify expedited review had Congress so provided; but Congress simply did not draft the statute in a way that distinguishes the DNC from any individual voter.
Consistent with FEC’s supervisory role, Congress provided an administrative complaint procedure in 2 U. S. C. §437g, through which the Democrats could have pursued their dispute with the PACs. The Democrats could have filed a complaint expressing their belief that “a violation [of the Fund Act] ha[d] occurred” based on the PACs’ independent expenditures in the 1980 Presidential election. § 437g(a)(l). If the FEC, “upon receiving a complaint... or on the basis of information ascertained in the normal course of carrying out its supervisory responsibilities, determines . . . that it has reason to believe that a person has committed, or is about to commit, a violation [of the Fund Act],” §437g(a)(2), it is obligated to investigate and, if it finds “probable cause to believe that any person has committed, or is about to commit, a violation,” to pursue various corrective and enforcement steps, which can ultimately involve civil and criminal proceedings in district court.
If the FEC dismissed the complaint or failed to act on it in 120 days, the Democrats could petition the District Court for the District of Columbia under §437g(a)(8) for a declaration that the FEC had acted contrary to law and for an order directing the FEC to pursue the complaint. If, and only if, the FEC failed to obey such an order, could the Democrats bring a civil action directly against the PACs to remedy the violation charged in their complaint.
Alternatively, the DNC or an individual voter could sue the FEC under 26 U. S. C. § 9011(b) to implement or construe the Act. This avenue, of course, is available to the *489Democrats without first pursuing or exhausting the §437g administrative complaint procedure, see § 9011(b)(2), but it would be worth pursuing only if the disagreement between the litigant and the FEC were over a matter of implementation or construction, and not routine enforcement. However, that is a judgment Congress made in establishing the statutory scheme.
We do not necessarily reject the District Court’s conclusion that the legislative history of the successive amendments to §437c(b)(l) indicates an intention by the word “exclusive” to centralize in one agency the civil enforcement responsibilities previously fragmented among various governmental agencies. But nowhere is there any indication that Congress previously expressed any intention that anyone other than Government agencies have enforcement responsibilities. Section 9011(b) certainly is not a source.of general private “enforcement” authority, as that word is conspicuously absent from § 9011(b), which speaks only of suits to “implement or construe.”2 We also do not believe that an intention to create a so-called “maximum enforcement regime,” calling for both Government and private enforcement, can be inferred from the fact that other congressional Acts, such as the Surface Mining Control and Reclamation Act of 1977, 30 U. S. C. § 1270, the Energy Policy and Conservation Act, 42 U. S. C. §6305, and the Clean Air Act, 42 U. S. C. §7604, expressly adopt such an enforcement scheme. Nor may it be inferred from the fact that the related FEC A has a different enforcement scheme than the Fund Act. Compare 2 U. S. C. §437d(e) and 26 U. S. C. § 9011(b). Such speculative inferences do not carry the day in the face of the contrary language of the Fund Act.
In view of our conclusion that the Democrats lack standing under the statute, there is no need to reach the Art. Ill issue *490decided by the District Court. Therefore, we turn to the merits of the FEC’s appeal of its unsuccessful declaratory judgment action against the PACs.
i — i l-H
NCPAC is a nonprofit, nonmembership corporation formed under the District of Columbia Nonprofit Corporation Act in August 1975 and registered with the FEC as a political committee. Its primary purpose is to attempt to influence directly or indirectly the election or defeat of candidates for federal, state, and local offices by making contributions and by making its own expenditures. It is governed by a three-member board of directors which is elected annually by the existing board. The board’s chairman and the other two members make all decisions concerning which candidates to support or oppose, the strategy and methods to employ, and the amounts of money to spend. Its contributors have no role in these decisions. It raises money by general and specific direct mail solicitations. It does not maintain separate accounts for the receipts from its general and specific solicitations, nor is it required by law to do so.
FCM is incorporated under the laws of Virginia and is registered with the FEC as a multicandidate political committee. In all material respects it is identical to NCPAC.
Both NCPAC and FCM are self-described ideological organizations with a conservative political philosophy. They solicited funds in support of President Reagan’s 1980 campaign, and they spent money on such means as radio and television advertisements to encourage voters to elect him President. On the record before us, these expenditures were “independent” in that they were not made at the request of or in coordination with the official Reagan election campaign committee or any of its agents. Indeed, there are indications that the efforts of these organizations were at times viewed with disfavor by the official campaign as counterproductive to its chosen strategy. NCPAC and FCM expressed their intention to conduct similar activities in support of President *491Reagan’s reelection in 1984, and we may assume that they did so.
As noted above, both the Fund Act and FECA play a part in regulating Presidential campaigns. The Fund Act comes into play only if a candidate chooses to accept public funding of his general election campaign, and it covers only the period between the nominating convention and 30 days after the general election. In contrast, FECA applies to all Presidential campaigns, as well as other federal elections, regardless of whether publicly or privately funded. Important provisions of these Acts have already been reviewed by this Court in Buckley v. Valeo, 424 U. S. 1 (1976). Generally, in that case we upheld as constitutional the limitations on contributions to candidates and struck down as unconstitutional limitations on independent expenditures.3
In these cases we consider provisions of the Fund Act that make it a criminal offense for political committees such as NCPAC and FCM to make independent expenditures in support of a candidate who has elected to accept public financing. Specifically, § 9012(f) provides:
“(1) ... it shall be unlawful for any political committee which is not an authorized committee with respect to the eligible candidates of a political party for President and Vice President in a presidential election knowingly and willfully to incur expenditures to further the election of such candidates, which would constitute qualified campaign expenses if incurred by an authorized committee of such candidates, in an aggregate amount exceeding $1,000.”
The term “political committee” is defined to mean “any committee, association, or organization (whether or not incorporated) which accepts contributions or makes expenditures for *492the purpose of influencing, or attempting to influence, the nomination or election of one or more individuals to Federal, State, or local elective public office.” . 26 U. S. C. § 9002(9). The term “qualified campaign expense” simply means an otherwise lawful expense by a candidate or his authorized committee “to further his election” incurred during the period between the candidate’s nomination and 30 days after election day. §§9002(11), 9002(12). The term “eligible candidates” means those Presidential and Vice Presidential candidates who are qualified under the Act to receive public funding and have chosen to do so. §§ 9002(4), 9003. Two of the more important qualifications are that a candidate and his authorized committees not incur campaign expenses in excess of his public funding and not accept contributions to defray campaign expenses. §§ 9003(b), 9012(b).
There is no question that NCPAC and FCM are political committees and that President Reagan was a qualified candidate, and it seems plain enough that the PACs’ expenditures fall within the term “qualified campaign expense.” The PACs have argued in this Court, though apparently not below; that § 9012(f) was not intended to cover truly independent expenditures such as theirs, but only coordinated expenditures. But “expenditures in cooperation, consultation, or concert, with, or at the request or suggestion of, a candidate, his authorized political committees, or their agents,” are considered “contributions” under the FECA, 2 U. S. C. § 441a(a)(7)(B)(i), and as such are already subject to FECA’s $1,000 and $5,000 limitations in §§441a(a)(l), (2). Also, as noted above, one of the requirements for public funding is the candidate’s agreement not to accept such contributions. Under the PACs’ construction, § 9012(f) would be wholly superfluous, and we find no support for that construction in the legislative history. We conclude that the PACs’ independent expenditures at issue in this case are squarely prohibited by § 9012(f), and we proceed to consider whether that prohibition violates the First Amendment.
*493There can be no doubt that the expenditures at issue in this case produce speech at the core of the First Amendment. We said in Buckley v. Valeo, supra, at 14:
“The Act’s contribution and expenditure limitations operate in an area of the most fundamental First Amendment activities. Discussion of public issues and debate on the qualifications of candidates are integral to the operation of the system of government established by our Constitution. The First Amendment affords the broadest protection to such political expression in order ‘to assure [the] unfettered interchange of ideas for the bringing about of political and social changes desired by the people.’ Roth v. United States, 354 U. S. 476, 484 (1957). . . . This no more than reflects our ‘profound national commitment to the principle that debate on public issues should be uninhibited, robust, and wide-open,’ New York Times Co. v. Sullivan, 376 U. S. 254, 270 (1964).”
The PACs in this case, of course, are not lone pamphleteers or street corner orators in the Tom Paine mold; they spend substantial amounts of money in order to communicate their political ideas through sophisticated media advertisements. And of course the criminal sanction in question is applied to the expenditure of money to propagate political views, rather than to the propagation of those views unaccompanied by the expenditure of money. But for purposes of presenting political views in connection with a nationwide Presidential election, allowing the presentation of views while forbidding the expenditure of more than $1,000 to present them is much like allowing a speaker in a public hall to express his views while denying him the use of an amplifying system. The Court said in Buckley v. Valeo, supra:
“A restriction on the amount of money a person or group can spend on political communication during a campaign necessarily reduces the quantity of expres*494sion by restricting the number of issues discussed, the depth of their exploration, and the size of the audience reached. This is because virtually every means of communicating ideas in today’s mass society requires the expenditure of money. The distribution of the humblest handbill or leaflet entails printing, paper, and circulation costs. Speeches and rallies generally necessitate hiring a hall and publicizing the event. The electorate’s increasing dependence on television, radio, and other mass media for news and information has made these expensive modes of communication indispensable instruments of effective political speech.” 424 U. S., at 19.
We also reject the notion that the PACs’ form of organization or method of solicitation diminishes their entitlement to First Amendment protection. The First Amendment freedom of association is squarely implicated in these cases. NCPAC and FCM are mechanisms by which large numbers of individuals of modest means can join together in organizations which serve to “amplif[y] the voice of their adherents.” Buckley v. Valeo, 424 U. S., at 22; NAACP v. Alabama, 357 U. S. 449, 460 (1958); Citizens Against Rent Control v. Berkeley, 454 U. S. 29Ó, 295-296 (1981). It is significant that in 1979-1980 approximately 101,000 people contributed an average of $75 each to NCPAC and in 1980 approximately 100,000 people contributed an average of $25 each to FCM.
The FEC urges that these contributions do not constitute individual speech, but merely “speech by proxy,” see California Medical Assn. v. FEC, 453 U. S. 182, 196 (1981) (Marshall, J.) (plurality opinion), because the contributors do not control or decide upon the use of the funds by the PACs or the specific content of the PACs’ advertisements and other speech. The plurality emphasized in that case, however, that nothing in the statutory provision in question “limits the amount [an unincorporated association] or any of its members may independently expend in order to advocate political views,” but only the amount it may contribute to *495a multicandidate political committee. Id., at 195. Unlike California Medical Assn., the present cases involve limitations on expenditures by PACs, not on the contributions they receive; and in any event these contributions are predominantly small and thus do not raise the same concerns as the sizable contributions involved in California Medical Assn.
Another reason the “proxy speech” approach is not useful in this case is that the contributors obviously like the message they are hearing from these organizations and want to add their voices to that message; otherwise they would not part with their money. To say that their collective action in pooling their resources to amplify their voices is not entitled to full First Amendment protection would subordinate the voices of those of modest means as opposed to those sufficiently wealthy to be able to buy expensive media ads with their own resources.
Our decision in FEC v. National Right to Work Committee, 459 U. S. 197 (1982) (NRWC), is not to the contrary. That case turned on the special treatment historically accorded corporations. In return for the special advantages that the State confers on the corporate form, individuals acting jointly through corporations forgo some of the rights they have as individuals. Id., at 209-210. We held in NRWC that a rather intricate provision of the FEC A dealing with the prohibition of corporate campaign contributions to political candidates did not violate the First Amendment. The prohibition excepted corporate solicitation of contributions to a segregated fund established for the purpose of contributing to candidates, but in turn limited such solicitations to stockholders or members of a corporation without capital stock. We upheld this limitation on solicitation of contributions as applied to the National Right to Work Committee, a corporation without capital stock, in view of the well-established constitutional validity of legislative regulation of corporate contributions to candidates for public office. NRWC is consistent with this Court’s earlier holding that a corporation’s *496expenditures to propagate its views on issues of general public interest are of a different constitutional stature than corporate contributions to candidates. First National Bank of Boston v. Bellotti, 435 U. S. 765, 789-790 (1978). In Bellotti, of course, we did not reach, nor do we need to reach in these cases, the question whether a corporation can constitutionally be restricted in making independent expenditures to influence elections for public office. Id., at 788, n. 26.
Like the National Right to Work Committee, NCPAC and FCM are also formally incorporated; however, these are not “corporations” cases because § 9012(f) applies not just to corporations but to any “committee, association, or organization (whether or not incorporated)” that accepts contributions or makes expenditures in connection with electoral campaigns. The terms of §9012(f)’s prohibition apply equally to an informal neighborhood group that solicits contributions and spends money on a Presidential election as to the wealthy and professionally managed PACs involved in these cases. See Citizens Against Rent Control v. Berkeley, supra, at 300 (Rehnquist, J., concurring).
Having concluded that the PACs’ expenditures are entitled to full First Amendment protection, we now look to see if there is a sufficiently strong governmental interest served by § 9012(f )’s restriction on them and whether the section is narrowly tailored to the evil that may legitimately be regulated. The restriction involved here is not merely an effort by the Government to regulate the use of its own property, such as was involved in United States Postal Service v. Greenburgh Civic Assns., 453 U. S. 114 (1981), or the dismissal of a speaker from Government employment, such as was involved in Connick v. Myers, 461 U. S. 138 (1983). It is a flat, across-the-board criminal sanction applicable to any “committee, association, or organization” which spends more than $1,000 on this particular type of political speech.
We held in Buckley and reaffirmed in Citizens Against Rent Control that preventing corruption or the appearance of corruption are the only legitimate and compelling govern*497ment interests thus far identified for restricting campaign finances. In Buckley we struck down the FECA’s limitation on individuals’ independent expenditures because we found no tendency in such expenditures, uncoordinated with the candidate or his campaign, to corrupt or to give the appearance of corruption. For similar reasons, we also find § 9012(f )’s limitation on independent expenditures by political committees to be constitutionally infirm.
Corruption is a subversion of the political process. Elected officials are influenced to act contrary to their obligations of office by the prospect of financial gain to themselves or infusions of money into their campaigns. The hallmark of corruption is the financial quid pro quo: dollars for political favors. But here the conduct proscribed is not contributions to the candidate, but independent expenditures in support of the candidate. The amounts given to the PACs are overwhelmingly small contributions, well under the $1,000 limit on contributions upheld in Buckley; and the contributions are by definition not coordinated with the campaign of the candidate. The Court concluded in Buckley that there was a fundamental constitutional difference between money spent to advertise one’s views independently of the candidate’s campaign and money contributed to the candidate to be spent on his campaign. We said there:
“Unlike contributions, such independent expenditures may well provide little assistance to the candidate’s campaign and indeed may prove counterproductive. The absence of prearrangement and coordination of an expenditure with the candidate or his agent not only undermines the value of the expenditure to the candidate, but also alleviates the danger that expenditures will be given as a quid pro quo for improper commitments from the candidate.” 424 U. S., at 47.
We think the same conclusion must follow here. It is contended that, because the PACs may by the breadth of their organizations spend larger amounts than the individuals in *498Buckley, the potential for corruption is greater. But precisely what the “corruption” may consist of we are never told with assurance. The fact that candidates and elected officials may alter or reaffirm their own positions on issues in response to political messages paid for by the PACs can hardly be called corruption, for one of the essential features of democracy is the presentation to the electorate of varying points of view. It is of course hypothetically possible here, as in the case of the independent expenditures forbidden in Buckley, that candidates may take notice of and reward those responsible for PAC expenditures by giving official favors to the latter in exchange for the supporting messages. But here, as in Buckley, the absence of prearrangement and coordination undermines the value of the expenditure to the candidate, and thereby alleviates the danger that expenditures will be given as a quid pro quo for improper commitments from the candidate. On this record, such an exchange of political favors for uncoordinated expenditures remains a hypothetical possibility and nothing more.
Even were we to determine that the large pooling of financial resources by NCPAC and FCM did pose a potential for corruption or the appearance of corruption, § 9012(f) is a fatally overbroad response to that evil. It is not limited to multimillion dollar war chests; its terms apply equally to informal discussion groups that solicit neighborhood contributions to publicize their views about a particular Presidential candidate.
Several reasons suggest that we are not free to adopt a limiting construction that might isolate wealthy PACs, even if such a construction might save the statute. First, Congress plainly intended to prohibit just what § 9012(f) prohibits— independent expenditures over $1,000 by all political committees, large and small.- Even if it did not intend to cover small neighborhood groups, there is also no evidence in the statute or the legislative history that it would have looked *499favorably upon a construction of the statute limiting § 9012(f) only to very successful PACs. Secondly, we cannot distinguish in principle between a PAC that has solicited 1,000 $25 contributions and one that has solicited 100,000 $25 contributions. Finally, it has been suggested that § 9012(f) could be narrowed by limiting its prohibition to political committees in which the contributors have no voice in the use to which the contributions are put. Again, there is no indication in the statute or the legislative history that Congress would be content with such a construction. More importantly, as observed by the District Court, such a construction is intolerably vague. At what point, for example, does a neighborhood group that solicits some outside contributions fall within § 9012(f)? How active do the group members have to be in setting policy to satisfy the control test? Moreover, it is doubtful that the members of a large association in which each have a vote on policy have substantially more control in practice than the contributors to NCPAC and FCM: the latter will surely cease contributing when the message those organizations deliver ceases to please them.
In the District Court, the FEC attempted to show actual corruption or the appearance of corruption by offering evidence of high-level appointments in the Reagan administration of persons connected with the PACs and newspaper articles and polls purportedly showing a public perception of corruption. The District Court excluded most of the proffered evidence as irrelevant to the critical elements to be proved: corruption of candidates or public perception of corruption of candidates. A tendency to demonstrate distrust of PACs is not sufficient. We think the District Court’s finding that “the evidence supporting an adjudicative finding of corruption or its appearance is evanescent,” 587 F. Supp., at 830, was clearly within its discretion, and we will not disturb it here. If the matter offered by the FEC in the District Court be treated as addressed to what the District Court *500referred to as “legislative facts,” we nonetheless agree with the District Court that the evidence falls far short of being adequate for this purpose.
Finally, the FEC urges us to uphold § 9012(f) as a prophylactic measure deemed necessary by Congress, which has far more expertise than the Judiciary in campaign finance and corrupting influences. In NRWC, 459 U. S., at 210, we stated:
“While [2 U. S. C.] §441b restricts the solicitation of corporations and labor unions without great financial resources, as well as those more fortunately situated, we accept Congress’ judgment that it is the potential for such influence that demands regulation. Nor will we second-guess a legislative determination as to the need for prophylactic measures where corruption is the evil feared.”
Here, however, the groups and associations in question, designed expressly to participate in political debate, are quite different from the traditional corporations organized for economic gain. In NRWC we rightly concluded that Congress might include, along with labor unions and corporations traditionally prohibited from making contributions to political candidates, membership corporations, though contributions by the latter might not exhibit all of the evil that contributions by traditional economically organized corporations exhibit. But this proper deference to a congressional determination of the need for a prophylactic rule where the evil of potential corruption had long been recognized does not suffice to establish the validity of § 9012(f), which indiscriminately lumps with corporations any “committee, association or organization.” Indeed, the FEC in its briefs to this Court does not even make an effort to defend the statute under a construction limited in reach to corporations.
While in NRWC we held that the compelling governmental interest in preventing corruption supported the restriction *501of the influence of political war chests tunneled through the corporate form, in the present cases we do not believe that a similar finding is supportable: when the First Amendment is involved, our standard of review is “rigorous,” Buckley v. Valeo, 424 U. S., at 29, and the effort to link either corruption or the appearance of corruption to independent expenditures by PACs, whether large or small, simply does not pass this standard of review. Even assuming that Congress could fairly conclude that large-scale PACs have a sufficient tendency to corrupt, the overbreadth of § 9012(f) in these cases is so great that the section may not be upheld. We are not quibbling over fine-tuning of prophylactic limitations, but are concerned about wholesale restriction of clearly protected conduct. See Broadrick v. Oklahoma, 413 U. S. 601 (1973).
The judgment of the District Court is affirmed as to the constitutionality of § 9012(f), but is reversed on the issue of the Democrats’ standing, with instructions to dismiss their complaint for lack of standing.
It is so ordered.
Justice Brennan joins only Part II of this opinion.
Mezvinsky did not pursue an appeal in this Court, though his name was inadvertently included in the notice of appeal filed by the Democratic Party and the DNC.
The Democrats implicitly conceded as much by amending their complaint to delete their initial request for injunctive relief.
In Buckley, The Chief Justice and Justice Blackmun would have struck down the limitations on contributions along with the limitations on independent expenditures. Justice White would have upheld both limitations.
