Finance breakdown

Disclosed funding shaping this race — both the money candidates raise themselves and the outside spending dropped by independent groups. Issue-ad spending by 501(c)(4) groups is excluded; the FEC doesn't require disclosure of it. See the note below for details.

What's counted, what isn't

Candidate-direct is each campaign's reported receipts on FEC Schedule A — individual contributions plus PAC contributions to the candidate's own committee — through the most recent filing.

Outside spending is independent expenditures on FEC Schedule E: money spent by PACs, super PACs, and party committees for or against a candidate, without legal coordination with the campaign. The committees listed under each candidate are the largest disclosed spenders on either side.

In-state vs out-of-state covers only itemized individual contributions — donations over $200, which are the only ones that carry a contributor address at the FEC. Sub-$200 unitemized donations (often a large share for grassroots campaigns) have no geography on file and are excluded, as is PAC money. So the percentages describe where a candidate's itemized individual money comes from, not where every dollar raised comes from.

Not counted: 501(c)(4) "social welfare" organizations run issue ads that frequently mention candidates by name but aren't classified as express advocacy under FEC rules — they file no Schedule E and don't appear in this breakdown. Press reporting on a race may cite figures that include this dark-money spending; ours doesn't.

About this race page

Candidate roster is sourced from the FEC's active-candidate list for the 2026 cycle. Fundraising totals reflect committee filings through the last reporting period.

Alignment % compares the candidate's extracted policy positions against your quiz answers. Positions are pulled from the candidate's campaign issues page by AI; we save the source quote for each position so you can verify the extraction. Candidates without a campaign issues page show position data pending — we're working through the roster and re-checking stale extractions every 90 days.

News coverage is from the GDELT 2.0 global news feed, filtered to a curated list of national, political, and regional outlets.
