Senate votes

119th Congress, through Sept 30, 2026

915 roll calls. Yea 264, Nay 591, Not voting 60.

How these are counted

Missed is Not Voting divided by every roll call the member was listed on, including quorum calls and procedural votes. It covers any absence, including illness and leave.

Party split: a roll call counts when the Democratic majority and the Republican majority voted opposite ways. That was 786 roll calls, and the member matched their own party on 773. We pick no votes ourselves.

Senate votes come from Voteview. Lewis, Jeffrey B., Keith Poole, Howard Rosenthal, Adam Boche, Aaron Rudkin, and Luke Sonnet (2026). Voteview: Congressional Roll-Call Votes Database. https://voteview.com/
