Where the money comes from

Inside IA versus everywhere else
48%
From IA · $1,728,787
52%
From outside IA · $1,845,014

Share of itemized receipts by the contributor state on each filing. A filing with no state recorded counts as outside IA, so the in-state share is a floor rather than an estimate. Out-of-state giving is ordinary and lawful; it is reported here because it is part of the public record and is not otherwise easy to see.

Cycles before 2022 are not yet loaded.

Itemized columns cover individual contributions over $200 in each FEC cycle currently loaded — not career totals. In-state share uses the contributor state on each filing; filings with no state recorded count as outside IA. Scores are Nokken-Poole dimension 1 from Voteview, re-estimated each Congress; Voteview reads the scale from liberal at −1 to conservative at +1. DonorTrail reports the score and rank and leaves the label to the source. FEC figures computed Oct 20, 2026.

What these records do and do not show

This page places two independent public records side by side: itemized campaign contributions reported to the Federal Election Commission, and roll-call votes published by the Clerk of the House and the Secretary of the Senate. The running tab lists FEC receipts and Voteview scores in adjacent columns; DonorTrail draws no link between them. DonorTrail does not assert that any contribution influenced any vote, and nothing here should be read as a claim of cause. Here is the record; the conclusions are yours to draw.
