How these are counted
Total receipts line of each candidate’s principal campaign committee, 2025-2026 cycle. Other sites may show career, six-year or all-committee totals, which differ. The spectrum is a published research score, not our rating. How this works. Record is wins and losses in the races in our results files, the same count as each profile.
