This is the record in our results files, FEC candidate lists and DIME, not a complete career. Results for other offices, earlier years and most primaries can be missing. A general that went to a runoff counts as neither a win nor a loss.

- Voted with own party when parties split
- 98.5%
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 462 roll calls, and the member matched their own party on 455. We pick no votes ourselves.
