“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 1145 donors. The other 1095 gave $2.1M combined.
Plus $71K from small donors giving under $200 each — those aren’t itemized by name.
Showing the 50 biggest of 436 donors. The other 386 gave $259K combined.
Plus $98K 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.

Outside groups have poured $6.5 million into Ohio's 15th District, a seat Republicans were supposed to hold easily
The Columbus Dispatch reports that outside PACs have spent more than $6.5 million over the past two months in Ohio's 15th District, where Republican Rep. Mike Carey faces Democrat Don Leonard — a remarkable total for a seat Carey won by 13 points in 2024. Per FEC independent-expenditure filings, left-leaning groups have spent about $3.9 million helping Leonard (about $2.6 million of it against Carey), while right-leaning groups have spent about $2.6 million helping Carey, including about $1 million from the Trump-aligned Safety & Affordability PAC. This is cumulative spending over two months, not a single new buy; Sabato's Crystal Ball moved the race from Safe Republican to Likely Republican at the end of September, and a House Majority PAC poll released Oct. 28 showed Leonard ahead by 3 points.

Unknown 'Conservatives for America' filer drops $100K pro-GOP ad across four House races
A brand-new independent-expenditure filer called 'Conservatives for America' (C90023870, Bethesda MD PO box) filed its first-ever FEC report Oct 20: a single $100,000 advertising buy via GOP firm Targeted Victory (disseminated Oct 19) supporting four House Republicans — Mike Carey (OH-15), Brad Finstad (MN-1), French Hill (AR-2), and Bryan Steil (WI-1). It is one $100,000 outlay, not $400,000 (a dual-purpose ad naming four candidates). No individual behind the filer is named in public FEC data, and F5 filers never file donor reports.

House Majority PAC memo: 'House battleground extends deep into Trump territory'
HMP's Oct 21 internal memo claims its polling shows Democrats competitive in 13 House districts Trump carried in 2024, releasing internal poll numbers for FL-13, IN-05, KY-06, MN-01, MO-02, MT-01, NC-09, NE-01, NV-02, NY-21, OH-15, TX-23 and TX-35 — all within single digits. Treat as partisan polling: it is HMP's own commissioned polling released to make the case for more fundraising, not independent data.

UDP's $55M war chest still sitting; J Street, DMFI, and anti-AIPAC groups place new general-election bets
AIPAC's super PAC entered September with $54.9 million in cash on hand but has disclosed only about $284,000 in general-election spending — mailers attacking Abdul El-Sayed in Michigan's Senate race — with its September monthly report due today and a pre-general report due Oct. 22. Meanwhile, the anti-AIPAC super PAC American Priorities spent $300,000 in October in Ohio's 15th District (backing Don Leonard, attacking incumbent Mike Carey) and $275,000 in Michigan's Senate race. J Street's super PAC reported $470,000 in digital ads against Mike Collins in Georgia's Senate race and on Oct. 20 announced new ads targeting AIPAC-endorsed Reps. Mariannette Miller-Meeks (IA-1) and Ryan Mackenzie (PA-7), while DMFI PAC spent $900,000 in late September backing Elaine Luria against Jen Kiggans in VA-2.
