How this works
Every number here comes from public filings with the Federal Election Commission. Nothing is estimated, scraped from news, or adjusted. Every member page links to the FEC records it's built from, so you can check any figure yourself.
The campaign chart
This chart covers money given directly to the member's own campaign committee, split the way the FEC reports it:
- Small donors
- People whose total giving to the campaign is $200 or less. Campaigns don't have to name these donors.
- Large donors
- People giving more than $200, capped by law at $3,500 per election in 2025–26 (primary and general count separately). Some PACs "bundle" or "earmark" checks from their members. That money is counted here, as individual donations, not under PACs.
- PACs
- Political action committees: those set up by corporations, unions and trade groups, ideological and single-issue PACs, and other politicians' leadership PACs. All of them are capped at $5,000 per election.
- Joint fundraising
- Money passed along from joint fundraising committees, which raise for several campaigns at once.
- Party, self & other
- Party committee contributions, the candidate's own money and loans, and other receipts.
Why there's no "corporations" or "foreign" slice
Corporations have been barred from giving directly to federal candidates since 1907. Foreign nationals, governments and companies are barred from giving anything at all. Corporate influence on a campaign arrives through company PACs, funded by employees and counted under PACs. A chart showing a "corporate" or "foreign" slice of a campaign's own money would be showing something the law says can't be there, or guessing.
Money spent around them
Since the 2010 Citizens United decision, super PACs and other outside groups can raise and spend unlimited money, including from billionaires and corporations, as long as they don't coordinate with the campaign. When they spend to help or defeat a specific candidate, they report it to the FEC as an "independent expenditure." That spending is what the second section shows. Click any spender to see its donors on FEC.gov.
What this doesn't show
- Dark money. Some nonprofits (501(c)(4) "social welfare" groups) run political ads without disclosing their donors. Some of this spending appears as independent expenditures, but the money behind it can't be traced.
- Leadership PACs a member controls but that aren't their campaign committee.
- Lobbying, stock trades, and jobs after leaving office. These are real channels of influence, but they aren't in FEC data.
- The very latest filings. The FEC processes reports in batches. Spending reported in the final weeks before an election can take time to show up here.
