“Individuals” covers both small-dollar (under $200) and large donors.
Every donor ranked by how much they gave, from the candidate’s own FEC filings — individuals, PACs, and party committees all in one list. Expand a candidate to see theirs, then tap any name to learn more about the donor.
Why are so many gifts exactly $10,000? That’s the legal maximum a PAC can give one candidate for the whole cycle — $5,000 for the primary plus $5,000 for the general — so many PACs give the max. Individuals can give up to $3,500 per election.
Showing the 50 biggest of 782 donors. The other 732 gave $1M combined.
Plus $35K from small donors giving under $200 each — those aren’t itemized by name.
Showing the 50 biggest of 349 donors. The other 299 gave $97K combined.
Plus $88K from small donors giving under $200 each — those aren’t itemized by name.
These figures come from the candidate’s own itemized FEC reports (2026 cycle, through the coverage date above), with amendments applied and refunds netted. Joint fundraising transfers are left out of the ranking: they’re pass-throughs, and the individual donations behind them are listed above. Bank interest, vendor refunds, and other non-donation receipts are excluded. Donor names are as reported — the same person can appear twice if their name was recorded differently. Independent spending on ads is never included here — see the Outside spending column.
