Voting analysis

Seth Moulton missed a larger share of House roll calls than all but three other members during this period.

The figure is a count of recorded participation. It attributes no cause, and the roll call itself never states one. What it does establish is that the rest of this page rests on a comparatively thin set of votes.

Three departures, no pattern

He supported a war powers resolution and an energy bill that most Democrats opposed, then voted against the consolidated appropriations act that most of them carried. Two crossings outward and one refusal inward, on three unrelated questions — too few, and too scattered, to describe a tendency.

All 3 roll calls where Seth Moulton voted against the House Democrat majority.
