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.
| Roll call | Date | Outcome | Their vote |
|---|---|---|---|
| H.Con.Res.84 Directing the President pursuant to section 5(c) of the War Powers Resolution to remove United States Armed Forces from Lebanon On Agreeing to the Resolution · roll call 201 | Jun 4, 2026 | Failed | Yea (party: Nay) |
| H.R.5587 HEATS Act On Passage · roll call 137 | Apr 23, 2026 | Passed | Yea (party: Nay) |
| H.R.7148 Consolidated Appropriations Act, 2026 On Passage · roll call 45 | Jan 22, 2026 | Passed | Nay (party: Yea) |
