Voting analysis

Three of Sean Casten's filings work the same argument from three angles: a public interest test for liquefied natural gas exports, a reporting requirement for carbon emissions that leave the country embedded in exports, and repeal of oil and gas tax subsidies. Together they treat fossil fuel policy as a question about accounting — who bears the cost, and whether the ledger currently records it.

1811
Bills cosponsored

Of the 50 most recent of those, 50 currently sit at Introduced.

Energy tops his classified subjects with finance close behind, and the remaining two filings sit on that second side: military voting, and transparency in companies with multiple share classes carrying unequal votes. That last one is a corporate governance question about who actually controls a listed company, and it is a subject almost nobody on this site legislates about.

Sponsored bills carry the Congressional Research Service's own subject classification. Sean Casten's cluster into: Energy (11), Finance and Financial Sector (10), Crime and Law Enforcement (4), Environmental Protection (4), Government Operations and Politics (3), Education (2).

Where he broke ranks

Five departures. He voted down the children's online safety act and a shrimping measure, both of which his caucus backed and the chamber passed. He crossed once, on fuel retailing. Two amendment votes finish the list.
