Campaign finance reform is not a single proposal. It is a landscape of distinct proposals with different legal theories, different political coalitions, and different levels of confidence in the available evidence about their effects. Some proposals address disclosure without touching spending. Some address spending through public amplification rather than restriction. Some require constitutional change. Some focus on institutional reform rather than substantive rules.
What follows is an account of each major category of proposal: what it would do, what the legal theory behind it is, where it currently stands politically, who supports and opposes it, and what the evidence suggests about its likely effects.
Disclosure-Only Approaches
The most legally durable category of reform involves disclosure requirements. Under the Buckley framework, disclosure requirements receive much more favorable treatment than spending restrictions because they do not directly limit the quantity of speech—they require transparency about who is speaking. The Supreme Court has consistently upheld disclosure as a legitimate government interest.
The DISCLOSE Act
The Democracy Is Strengthened by Casting Light On Spending in Elections Act—known as the DISCLOSE Act—has been introduced in Congress in various forms since 2010, in direct response to the Citizens United decision. The 2023 version, introduced by Senator Sheldon Whitehouse with 52 Democratic co-sponsors, would require covered organizations (corporations, labor organizations, political organizations) to file reports within 24 hours disclosing campaign expenditures over $10,000 during an election cycle, and would require disclosure of donors who contributed $10,000 or more to organizations making such expenditures.
The bill directly targets dark money: it would require the “beneficial ownership” tracing that currently allows organizations to route contributions through intermediaries while the original source remains hidden. The Campaign Legal Center has argued that a recent D.C. District Court decision established that existing law already requires more disclosure than the FEC has been enforcing, making the DISCLOSE Act an effort to codify and expand what should already be happening.
The 2023 bill was referred to the Senate Rules and Administration Committee and has not received a floor vote. It received no Republican co-sponsors in its most recent form. Senate Republicans have consistently blocked the bill, arguing that disclosure requirements can be used to harass donors and suppress political speech through intimidation.
The case for the DISCLOSE Act does not require accepting that it will solve the underlying money-in-politics problem. It is a transparency measure, not a spending limit. Its most significant likely effect is informational—enabling journalists, researchers, and citizens to trace the connections between funding sources and political actors that are currently hidden behind nonprofit structures.
Beneficial Ownership Requirements
Separate from the DISCLOSE Act, there have been legislative and regulatory efforts to require disclosure of the actual individuals who control or fund political organizations, rather than allowing entities to appear as the nominal donor while their own funders remain unknown. The Corporate Transparency Act, enacted in 2021, created beneficial ownership reporting requirements for business entities—requirements that have faced legal challenges on different grounds. Similar principles applied to political organizations would close a significant dark money loophole.
Public Financing Proposals
Public financing proposals take several distinct forms, each with different legal theories and evidence bases.
Small-Dollar Matching: The NYC/NY Model and Federal Legislation
The small-dollar matching approach provides public funds to amplify small private contributions rather than replacing private fundraising entirely. The model is drawn directly from New York City’s program, which has operated since 1988, and from New York State’s program, which launched in 2024.
At the federal level, the primary legislative vehicle has been the For the People Act (H.R. 1), which included a 6-to-1 matching system for small donations to House candidates. The Freedom to Vote Act, introduced in 2021, included a similar provision: a 6-to-1 match on contributions up to $200 per donor, funded by a surcharge on certain corporate and individual penalties and settlements paid to the federal government—structured specifically to avoid using general appropriations.
The legal theory supporting matching programs is that they are additive—they use government funds to amplify certain kinds of speech rather than suppressing any speech. The Supreme Court upheld public financing in Buckley v. Valeo as a mechanism that “facilitate[s] and enlarge[s] public discussion and participation in the electoral process.” Matching programs have not been challenged successfully under this framework.
The evidence for matching programs’ effects comes primarily from New York City’s decades of experience and New York State’s first cycle. According to Brennan Center research on the 2024 New York State program, small donor participation more than doubled, the share of candidate funding from large donations dropped from 70-72 percent to 38 percent, and candidates in lower-income districts participated at rates comparable to those in wealthier districts. The NYC program has shown, across multiple cycles, that matching produces geographic broadening of donor pools—90 percent of census blocks had at least one small donor to city council candidates, compared to 30 percent for state assembly candidates without the program.
The political status of federal matching legislation is blocked. The For the People Act and Freedom to Vote Act passed the House in the current partisan configuration but failed in the Senate, where they received no Republican support and could not overcome a filibuster.
Supporters of matching programs argue they work with existing constitutional doctrine rather than requiring doctrinal change. Opponents, including most congressional Republicans, argue that public financing of campaigns is an inappropriate use of government funds.
Clean Elections / Full Public Financing
The full public financing model—providing complete funding to qualifying candidates who raise seed money and agree not to accept private contributions—was pioneered in Maine (1996) and Arizona (1996) at the state level. The federal government has not adopted a full public financing system for Congress, though the presidential public financing program (largely abandoned by major candidates since 2008) was of this general character.
Full public financing severs the connection between private fundraising and candidacy entirely for participating candidates. The documented effects include reduced time spent fundraising, a broadened candidate pool in early program years, and a measurably different donor pool composition. The evidence on whether it changes legislative behavior is more limited and methodologically difficult to establish.
The legal status of full public financing is secure—Buckley upheld voluntary public financing programs, and the Supreme Court has reaffirmed that their constitutionality is established. The challenge to Arizona’s program in Arizona Free Enterprise Club v. Bennett (2011) successfully struck down the matching funds trigger but left the core program intact.
Tax Credits for Small Donations
A third public financing approach uses the tax code to subsidize small donations rather than providing direct matching funds. The Democracy For All Act has included provisions for refundable tax credits for small political contributions, structured to benefit donors who might not otherwise itemize deductions. The logic is that a tax credit makes a $50 donation effectively cost-free for the donor, significantly lowering the financial barrier to participation without creating a direct government funding relationship with candidates.
Tax credit approaches are politically somewhat more tractable than direct public funding because they operate through the familiar mechanism of tax incentives. They also have distributional limitations: a refundable credit helps lower-income donors, but it is most straightforwardly accessible to those who file taxes and understand the credit’s availability.
Contribution Limit Tightening
Under current Supreme Court doctrine, contribution limits are constitutionally permissible as long as they are not set so low as to deprive candidates of adequate resources. Limits on direct contributions to candidates—currently $3,300 per candidate per election at the federal level—have been upheld consistently. What is not permissible, under current doctrine, are limits on independent expenditures by outside groups.
Tightening contribution limits is legally available without a constitutional amendment, but its practical significance is limited by the outside spending environment. If contribution limits prevent large donors from giving directly to candidates but those donors can give unlimited amounts to super PACs that run ads independently supporting those candidates, the limits constrain one channel while leaving others open. The practical effect of tightening contribution limits in isolation, without addressing outside spending, is therefore limited.
Some reform proposals pair tightened contribution limits with enhanced anti-coordination rules—rules designed to prevent the functional equivalent of coordination between candidates and nominally independent super PACs. The FEC has consistently failed to enforce existing coordination rules aggressively, which limits the operative significance of that approach in the current regulatory environment.
Constitutional Amendment Approaches
The most far-reaching reform proposals involve a constitutional amendment that would restore Congress’s and states’ authority to regulate campaign spending—authority that the Supreme Court’s interpretation has largely removed.
Multiple amendment versions have been introduced in Congress. The Democracy for All Amendment, introduced by Senator Jeanne Shaheen, would empower Congress and states to set reasonable, viewpoint-neutral campaign finance rules and limit corporate spending. The Citizens Over Corporations Amendment, introduced by Senator Adam Schiff and Representatives Joe Neguse, Jim McGovern, and Summer Lee, would explicitly distinguish between natural persons and corporations, permitting Congress and states to prohibit corporations from spending money to influence elections.
According to polling by American Promise, 77 percent of registered voters support a constitutional amendment to allow states and Congress to reasonably limit money in elections, with 82 percent viewing the influence of money in politics as a threat to American democracy. University of Maryland public consultation research found 75 percent bipartisan support for a constitutional amendment—including 66 percent of Republicans.
The path to a constitutional amendment is the most demanding in the political system. An amendment requires two-thirds approval in both chambers of Congress (or a constitutional convention called by two-thirds of state legislatures) and ratification by three-fourths of states (38 states). No campaign finance amendment has come close to meeting either threshold in Congress. Supporters of the amendment approach argue that this is a long-cycle political project—one that requires building public and legislative consensus over years before a viable amendment can advance.
State-Level Reform as a Strategy
Given the federal impasse, state-level reform has become an increasingly significant strategic focus for the reform community. The 2022 Arizona Proposition 211, which passed with 72 percent of the vote, required disclosure of original funding sources for large political spenders—a state-level dark money disclosure rule of the type that has repeatedly failed in Congress. Maine’s repeated citizen initiative victories demonstrate that ballot initiative processes can produce reform outcomes that legislative processes cannot.
State-level public financing expansions—in Connecticut, Hawaii, Maryland, and other states—represent ongoing efforts to build a body of evidence and political experience that could support federal reform over time. The limitations of this strategy include the federal campaign finance preemption of state rules for federal elections, and the state preemption of local rules discussed elsewhere in this hub.
FEC Structural Reform
The Federal Election Commission’s structural paralysis has been a persistent subject of reform proposals. The six-commissioner, bipartisan-parity structure requires four votes for any enforcement action—a design that, in practice, produces deadlock along party lines on most contested matters.
Brennan Center proposals for FEC reform have included changing the commission to an odd number of commissioners—five or seven—eliminating the structural guarantee of a tie, and requiring that commissioners be genuinely nonpartisan rather than politically appointed. H.R. 1 included provisions for an FEC with five commissioners and enhanced independence requirements.
Opponents of FEC reform argue that a structural change giving one party control over enforcement would produce a politically weaponized agency rather than an effective one. This is a real institutional design problem—the solution to partisan deadlock is not self-evident. A commission that enforces aggressively but politically could produce worse outcomes than a deadlocked one, depending on which party controls enforcement and whether commissioners exercise independent judgment.
What the current structure has demonstrably produced is an agency that does not enforce the laws it exists to enforce. That outcome also has costs, including the normalization of violations that face no consequence and the erosion of whatever deterrence effect the law might otherwise create.
The Landscape as a Whole
The reform proposals currently on the table range from measures that are legally available and politically blocked (DISCLOSE Act, matching funds), to measures that require constitutional change and are structurally difficult (amendment approaches), to institutional reforms with uncertain design implications (FEC restructuring), to state-level strategies that work around the federal impasse but cannot address it.
None of these proposals is a complete solution to the problems the reform movement identifies. Each addresses some dimension of the current system while leaving others unchanged. The most legally durable proposals—disclosure, public financing—cannot by themselves limit outside spending. The proposals that could limit outside spending—constitutional amendments, statutory spending caps—face either legal barriers under current doctrine or political barriers that have prevented legislative action for more than fifteen years.
Understanding what is on the table requires understanding both what each proposal would do if enacted and the path—legal, political, and institutional—that would be required to enact it.
