In Buckley v. Valeo, 424 U.S. 1 (1976), the Supreme Court held that the government may cap how much a person gives directly to a federal candidate but may not cap how much a person, group, or candidate spends to speak about an election. Issued January 30, 1976, the unsigned opinion reviewed the Federal Election Campaign Act of 1971 and its 1974 amendments and drew a line between contributions and expenditures that still governs American campaign finance today.1Federal Election Commission. Buckley v. Valeo
What the 1974 Law Tried to Do
The 1974 amendments were the most sweeping campaign finance reforms Congress had ever passed. They capped individual donations to candidates, capped what campaigns could spend, capped what candidates could spend from personal wealth, capped independent spending by outside supporters, required detailed public disclosure of donors and expenditures, created a voluntary public financing system for presidential campaigns, and established the Federal Election Commission to enforce it all.1Federal Election Commission. Buckley v. Valeo
An ideologically mixed group of plaintiffs sued. Senator James Buckley of New York, former Senator Eugene McCarthy’s presidential committee, donor Stewart Mott, the Libertarian Party, and conservative organizations all argued that the law violated the First Amendment.2Justia Law. Buckley v. Valeo, 424 U.S. 1 (1976) They sued Francis Valeo, then Secretary of the Senate and an ex officio member of the new commission.
The core legal question was whether limiting political money limits political speech. The Court did not adopt the shorthand that money is speech. It said something narrower: producing and distributing a political message in a modern society costs money, so limiting spending inevitably limits the quantity of communication that reaches voters.2Justia Law. Buckley v. Valeo, 424 U.S. 1 (1976) The government defended the law on two grounds: preventing corruption and equalizing the voices of rich and poor. The Court accepted the first and rejected the second, calling the idea of leveling political influence foreign to the First Amendment. From that split flowed the rest of the decision.
Contribution Limits: Upheld
The 1974 law capped individual donations to a federal candidate at $1,000 per election, capped donations to political committees at $5,000, and imposed a $25,000 overall annual ceiling on what a person could give across all federal candidates and committees combined.3Legal Information Institute. Buckley v. Valeo The Court upheld all three.
The reasoning turned on corruption. A large check handed directly to a candidate creates the clearest risk of a transactional relationship, and even without proof of a specific bargain, outsized donations create an appearance of influence that erodes public trust. The Court acknowledged that giving money signals support for a candidate’s ideas, but it treated that expressive value as less directly protected than a person’s own speech. A contribution cap does not stop anyone from volunteering, speaking publicly, or spending independently. It only caps the symbolic act of handing money to a campaign.
Those 1976 dollar figures have changed. For the 2025–2026 cycle, an individual can give up to $3,500 per election to a federal candidate, $5,000 per year to a traditional PAC, and $44,300 per year to a national party committee.4Federal Election Commission. Contribution Limits for 2025-2026 The $25,000 aggregate annual ceiling that Buckley upheld is gone, struck down in McCutcheon v. FEC in 2014.
Spending Limits: Struck Down
The Court struck down the caps on overall campaign spending, on candidates’ use of their own money, and on independent expenditures by outside supporters.1Federal Election Commission. Buckley v. Valeo When a person spends their own money to print flyers, buy ads, or travel to rallies, they are engaging in their own speech, and capping that spending directly reduces what they can say.
The distinction from contributions was central. A contribution passes through the candidate, who decides what message to fund. An independent expenditure is the speaker’s own voice, and because no money changes hands between the spender and the candidate, the Court saw far less risk of a corrupt bargain. Without a corruption rationale, the government had no interest strong enough to override the First Amendment. The Court also rejected the equalization argument outright: the Constitution protects the right to speak as much as one chooses, even if some speakers can afford to speak more.
The Court gave the personal-funds cap particular attention. If a candidate cannot draw on personal wealth, that candidate depends entirely on fundraising, which itself carries the corruption risks the law was meant to prevent. The Court called this self-defeating and struck the personal-funds limit with the rest.
Disclosure: Upheld
Where the Court split on limits, it was nearly unanimous on transparency. The 1974 amendments required political committees to record the identity of anyone giving more than $10, publicly disclose anyone giving more than $100, and report the source and purpose of expenditures over $100.3Legal Information Institute. Buckley v. Valeo The Court upheld disclosure as serving three interests: informing voters, deterring corruption by exposing financial relationships, and generating the data needed to enforce the other rules.
The justices recognized that forced disclosure can chill political activity, particularly for supporters of unpopular or minor parties, and left open an exemption for groups that could show a reasonable probability of harassment or retaliation. Today, disclosure obligations are more granular. A political committee making independent expenditures of $1,000 or more within 20 days of an election must file with the FEC within 24 hours, and each additional $1,000 triggers another filing.5Federal Election Commission. 24-Hour Reports
The Federal Election Commission Was Restructured
The 1974 law gave the FEC eight members: two picked by the President pro tempore of the Senate, two by the Speaker of the House, two by the President, plus the Secretary of the Senate and the Clerk of the House as non-voting members.3Legal Information Institute. Buckley v. Valeo The Court struck that scheme down under the Appointments Clause of Article II, which requires that officials exercising significant federal authority be appointed by the President.6Library of Congress. Overview of Appointments Clause Letting congressional leaders choose the commissioners who would enforce election law against those same leaders was a structural problem. Congress responded by making all six voting commissioners presidential nominees confirmed by the Senate, which is still the process today.
Presidential Public Financing Was Allowed
The Court upheld the voluntary public financing system for presidential campaigns, funded by the tax return checkoff. Primary candidates could receive federal matching funds, and general election nominees could receive a lump-sum grant, in exchange for accepting spending limits. Because participation was voluntary, the attached spending caps did not violate the First Amendment: a candidate who wanted to spend without limits could simply decline the public money.1Federal Election Commission. Buckley v. Valeo To qualify for primary matching funds, a candidate must raise more than $5,000 in contributions of $250 or less in each of at least 20 states.7Federal Election Commission. Public Funding of Presidential Elections No major-party nominee has accepted general election public financing since 2008, because the cap that comes with it is now well below what campaigns raise privately.
The “Magic Words” Footnote
To decide which independent communications fell under the law, the Court drew a line between express advocacy, which explicitly urges voters to elect or defeat a named candidate, and issue advocacy, which discusses policy without telling anyone how to vote. A footnote listed the phrases that qualify as express advocacy: “vote for,” “elect,” “support,” “cast your ballot for,” “vote against,” “defeat,” and “reject.”2Justia Law. Buckley v. Valeo, 424 U.S. 1 (1976)
For decades, lower courts read this to mean that any ad avoiding those magic words counted as issue advocacy, no matter how obvious its electoral purpose. A group could air a brutal attack ad two weeks before Election Day and escape both spending rules and disclosure entirely, as long as it never said “vote against.” Congress tried to close the gap with the Bipartisan Campaign Reform Act of 2002, which created a broader category called electioneering communications.
How Later Cases Built on Buckley
The contribution-versus-expenditure line has held up for half a century. Three later decisions reshaped what sits on either side of it.
Citizens United v. FEC (2010)
Citizens United extended Buckley’s protection of independent spending to corporations and unions, holding that the government cannot restrict political speech based on the speaker’s corporate identity. The Court struck down the federal ban on corporate and union independent expenditures that had been in place since 2002 and relied explicitly on Buckley’s finding that independent spending does not pose the same corruption risk as direct contributions.8Justia Law. Citizens United v. FEC, 558 U.S. 310 (2010)
SpeechNow.org v. FEC (2010)
The D.C. Circuit answered a follow-up question that same year: if independent expenditures cannot be limited, can the government limit contributions to groups that make only independent expenditures? The court said no. Because the money would be spent independently rather than given to candidates, Buckley’s corruption rationale did not apply.9Federal Election Commission. Speechnow.org v. FEC The ruling produced Super PACs, which can accept unlimited donations from individuals, corporations, and unions as long as they spend independently and do not coordinate with candidates. Disclosure and registration requirements survived, so the money is unlimited but reported.
McCutcheon v. FEC (2014)
McCutcheon revisited the aggregate annual ceiling that Buckley had upheld in 1976. The Court struck it down, finding that it bore too little connection to preventing corruption once modern anti-circumvention rules were in place.10Justia Law. McCutcheon v. FEC, 572 U.S. 185 (2014) The per-candidate limits survived, but donors can now give to as many candidates and committees as they wish.
Why the Framework Endures
Every major campaign finance case since 1976 has started from the same premise: contributions can be capped because they risk corruption, but independent spending cannot be capped because it is the speaker’s own voice. Super PACs, dark money nonprofits, and billion-dollar presidential campaigns all operate within lines Buckley drew. Critics on the left argue the framework lets wealth dominate elections. Critics on the right argue that even the contribution limits Buckley upheld restrict political speech more than the First Amendment allows. Neither side has moved the Court off the basic architecture, which is why anyone trying to understand how American elections are financed has to start with this case.
