Data as of 2026-07-06 · Source: U.S. Senate roll-call records

This project draws on 4 sources. The U.S. Senate’s official roll-call records are the backbone — they are the primary source for all 1542 votes. The others provide optional context or attributed third-party analysis. The current dataset was generated on 2026-07-06 and covers the 4 congressional sessions of Fetterman’s tenure.

Congress.gov API

Bill context (optional enrichment)

When available, used to add bill titles, sponsors, and policy areas. The site is built to work fully without it; where context is unavailable, fields are left blank rather than guessed.

GovTrack

Third-party analysis (attributed)
