Money: FEC bulk data, through Oct 14. One or more are matched to the FEC by name, party and seat, so a total could belong to someone else.
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. Hayes: $80,534 received, $11,274 cash on hand. Lee: $1,630,368 received, $1,713,225 cash on hand. The spectrum is a published research score, not our rating. How this works. Wins and losses count the races in our results files, the same as each profile.
