Sitting member of Congress · Mike Thompson

- Recorded yea or nay on 24 of the 24 key House floor votes captured in Hugin's snapshot

Linked to this filing by its exact FEC candidate ID (H8CA01109) in the congress-legislators roster of Oct 21, 2026. Votes are one key floor vote per bill on bills named in contractor lobbying reports (Oct 29, 2026); committee seats are the roster as of Oct 24, 2026; money counts are FEC reports for 2026 as of Oct 24, 2026. These are what Hugin's snapshots captured, not complete records, and none of them is a score or evidence of motive.

FEC bulk data read November 4, 2026. Campaign totals come from each filing's own FEC summary through its latest processed report. Outside spending is independent expenditures itemized in committee reports in the FEC bulk files, primaries included; late 24- and 48-hour reports, party coordinated spending, communication costs and groups that do not report to the FEC are not included. Outside spending is, by law, made without coordinating with the candidate, and it is not the candidate's money. A contribution or expenditure is not evidence of a vote, favor or wrongdoing.
