Questions worth asking.

Money shows who backed a campaign, not how a person will act. Compare it with what they did and said: their votes or official actions if they have held office, their own statements, and their answers to a finding. Use the same questions for every candidate.

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. This page identifies the filing by its FEC candidate ID; a person can hold more than one filing.
