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. Calvert: $7,050,383 received, $980,391 cash on hand. Kim: $10,148,196 received, $910,973 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.
