The marker is the one published measure below. The middle means centrist on that measure’s own scale, not the middle of Congress. How this works

By donors (CFscore, 2024 cycle)

Research estimate from Stanford DIME 4.0. Source

Method and limits

Published score 1.204 on a scale from −2.0 to 2.0, where 0 is the center. 1,855 donors. License: ODC-BY 1.0.

Places a candidate by who gave them money; candidates who share donors sit close together.

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.

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 840 roll calls, and the member matched their own party on 821. 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/
