Sources and notes
Campaign finance data comes from FEC.gov filings, while available vote records come from Congress.gov and the U.S. Senate roll call feed. Figures stay as reported by those sources. House votes come from Congress.gov. Senate votes come from the official roll call feed. Coverage may be incomplete for some profiles. Recent profile snapshots are reused briefly so repeat views stay fast and consistent.
