Why this matters

Cross-caucus voting is one of the cleanest indicators of a member’s willingness to break from party leadership when conscience, district, or coalition demands it. It’s not a left-right axis — it’s a caucus-discipline axis. See methodology for how we compute this.

What we don’t show

We don’t classify why a member broke from their caucus. The reasons can range from principled dissent to district pressure to procedural maneuvering. We surface the data; you bring the interpretation.
