Leaderboards

Senator rankings across key legislative metrics — 2025–2026 session

A note on majority leader power. The Senate Majority Leader controls which bills come to the floor for a vote. This affects several metrics on this page: party loyalty and lone-wolf counts are measured only against bills the majority leader chose to schedule — a sample that skews toward the majority party’s agenda. Co-sponsorship counts are more independent, but senators whose bills are routinely scheduled may attract more co-sponsors precisely because colleagues know those bills will move. The Floor Access Rate leaderboard at the bottom of this page makes the scheduling gap explicit.

Floor Access Rate

Of each senator’s sponsored bills (excluding resolutions, min 20), what percentage reached a floor vote?
