Shane Lewis on fec.gov. Zoe Lofgren on fec.gov. 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. 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.
