A PAC can give at most $10K per cycle directly to a candidate. But when individuals route donations through a PAC acting as conduit, there’s no cap on how many donors can be bundled. That’s where the real money moves — not from the PAC’s treasury, but from individuals the PAC steered to the candidate. How conduits work →

* AIPAC-linked money is already counted in the rows above — it flags the pro-Israel share, not extra money.
† Independent spending on ads for or against a candidate. It never goes to their campaign.
“Individuals” covers both small-dollar (under $200) and large donors.
Who are the biggest 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 3072 donors. The other 3022 gave $1.9M combined.
Plus $1.2M 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.
