Explore campaign finance data across all federal election cycles from 2000 to 2024. See total fundraising, candidate counts, and party breakdowns for each election year.
A federal election cycle covers a two-year period ending in an even-numbered year. Presidential elections occur every 4 years, while all House seats and one-third of Senate seats are up for election every 2 years.
All campaign finance data comes from the Federal Election Commission (FEC), which requires candidates and committees to report all contributions and expenditures.
Presidential elections (every 4 years) include races for President, Senate, and House. Midterm elections (the years between) include only Senate and House races.
