Maverick Watch — Members Crossing Party Lines

Maverick Watch — Members Crossing Party Lines

On most votes, party discipline is near-total. On a few — close votes, conscience issues, regional concerns — members break ranks. Those breaks are often more politically meaningful than the unanimous-bloc votes that get the headlines.

This page tracks every member who voted against their party’s majority on the 50 most consequential votes of the 119th Congress, weighted by how close each vote was.

Frequently Asked

How is “consequential” defined?

Votes weighted by margin (close votes count more), bill substance (laws ranked higher than procedural motions), and chamber (final passage votes ranked higher than committee votes).

Is this the same as “moderate” or “centrist”?

Not exactly. A member can be ideologically extreme but cross the aisle frequently on specific issues. Maverick score measures behavior, not ideology.

How is the score calculated?

Each cross-party vote earns points proportional to (1) how rare the cross was within the member’s party for that vote, and (2) how close the overall vote was. Summed across all votes, normalized to 0-100.

Does maverick voting predict election outcomes?

Mixed evidence. Some districts reward visible independence; others punish it. We track the votes; we don’t predict the elections.
