Inside CA versus everywhere else
81%
From CA · $648,871
19%
From outside CA · $154,503

Share of itemized receipts by the contributor state on each filing. A filing with no state recorded counts as outside CA, 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.

Nokken-Poole scores are re-estimated for each Congress, so they can move as a member’s voting changes. They are derived from roll-call votes alone and say nothing about why a member voted as they did. Voteview, which publishes these scores, reads the first dimension as running from liberal at −1 to conservative at +1; DonorTrail reports the position and the rank, and leaves the label to the source.

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. 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.
