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 399 roll calls, and the member matched their own party on 387. We pick no votes ourselves.
