Analysis
Original analysis, computed from every recorded vote in our corpus.
By Dallas AI Metrics, LLC · Analysis as of 2026-08-04 · Computed from 440 roll calls across 526 members · Methodology
Every figure in this section is computed from our own vote corpus — 440 roll calls covering 526 voting members of Congress, rebuilt each time the underlying data refreshes. Nothing here is a reprint of a government page.
The Defection Index
Which members break from their own party most often — and how rarely that happens at all.
Where Bills Go to Die
Almost every bill introduced in Congress never becomes law. Here is the shape of the funnel.
What Congress Actually Works On
Every bill carries a subject classification. Together they show where legislative attention goes.
Delegation Cohesion
Some state delegations vote as a bloc. Others barely agree with themselves.
The Committee Power Map
Where committee seats concentrate, and who holds the gavels.
Amendments vs. Final Passage
The same members vote differently depending on what kind of question is in front of them.
The Bills Both Parties Backed
How often a majority of both parties lands on the same side of a question.
Executive Action Tracker
Executive orders and signed legislation, by volume and subject.
Freshman vs. Veteran
Whether time served changes how a member votes.
Participation Rates
How often members are recorded as not voting — and what that number cannot tell you.
