Voting analysis
Martin Heinrich is ranking member of the energy and natural resources committee, sits ex officio on three of its subcommittees, and is ranking member of the legislative branch appropriations panel. Energy is both his jurisdiction and, in the filings, his subject.
Sponsored bills carry the Congressional Research Service's own subject classification. Martin Heinrich's cluster into: Armed Forces and National Security (1), Emergency Management (1), Energy (1), International Affairs (1), Labor and Employment (1), Native Americans (1).
The filings
Two of them address the same emerging problem from different angles: clarifying federal jurisdiction over connecting very large electrical loads to the transmission system, and managing grid connection and congestion. Data centres and industrial demand are arriving faster than interconnection rules were written for, and both bills are about that. Alongside them sit expanded Medicare coverage for psychological and behavioural health, home-based care for rural veterans, and a path act.
Of the 8 most recent of those, 8 currently sit at Introduced.
Where he broke ranks
Four departures carry a single measure through passage, cloture twice and an amendment folded in. Two joint resolutions and two adopted Republican amendments follow the same outward direction. Only two go the other way: an amendment from a colleague in his caucus that he voted down, and a cloture motion on proceeding to a surveillance bill that he declined.
