How Campaign Finance Changed Over Time: A Timeline

1974 — Federal Election Campaign Act Amendments
After Watergate, Congress strengthened federal campaign finance law. The 1974 amendments created contribution limits, expanded disclosure requirements, established public financing for presidential campaigns, and set up the Federal Election Commission to administer and enforce federal campaign finance rules.

1976 — Buckley v. Valeo
The Supreme Court reviewed the new campaign finance rules and drew an important line between contributions and expenditures. The Court allowed limits on direct contributions to candidates, but struck down several limits on campaign spending and independent spending. The decision helped establish that spending money to communicate political messages can be protected by the First Amendment.

1978 — First National Bank of Boston v. Bellotti
The Supreme Court ruled that Massachusetts could not stop corporations from spending money to express views on ballot measure issues. The decision strengthened the idea that political speech may be protected even when the speaker is a corporation or association.

2002 — Bipartisan Campaign Reform Act
The Bipartisan Campaign Reform Act, also called McCain-Feingold, was a major federal campaign finance law. It restricted “soft money” donations to national political parties and created new rules for certain broadcast ads that name federal candidates close to an election. The law reflected concern that large donations and election-related advertising could affect access, influence, and public trust.

2010 — Citizens United v. FEC
The Supreme Court ruled that the government could not ban corporations and unions from making independent political expenditures. Independent expenditures are political spending that supports or opposes candidates but is not coordinated with a candidate’s campaign. The decision changed campaign finance by expanding the ability of corporations, unions, and outside groups to spend money on election-related messages.

2010 — SpeechNow.org v. FEC
A federal appeals court ruled that groups making only independent expenditures could not be limited in how much money they raised for that spending. Together with Citizens United, this decision helped create the legal foundation for super PACs, which can raise and spend unlimited amounts of money as long as they do not coordinate directly with candidates.

2014 — McCutcheon v. FEC
The Supreme Court struck down the overall limit on how much one person could give to all federal candidates, parties, and PACs combined during a two-year election cycle. Limits on contributions to a single candidate or committee remained, but individuals could now contribute to more candidates and committees overall.

2020 — Federal Election Spending Reaches Record Levels
The 2020 federal election cycle became the most expensive in U.S. history, with total spending estimated at more than $14 billion. The spending reflected growth in candidate fundraising, party spending, and outside spending by groups such as super PACs.

2022 — Billionaire Spending Passes $1 Billion in the Midterms
Reports on the 2022 midterm elections found that billionaire political spending passed $1 billion for the first time in a midterm cycle. This became part of a larger debate over whether campaign finance rules allow wealthy donors to have too much influence in elections.

2024 — Outside Spending and Super PAC Activity Continue to Grow
The 2024 election cycle showed continued growth in outside political spending. Super PACs and other outside groups played a major role in funding political messages, showing how campaign finance has become increasingly connected to independent spending outside candidate campaigns.

2025 — Public Concern About Money in Politics Remains High
A Pew Research Center survey found that roughly seven in ten Americans viewed the role of money in politics as a very big problem. This shows that campaign finance is not only a legal issue; it is also a public trust issue connected to how people view elections, representation, and democratic participation.
