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.
