Voting analysis

Taxation accounts for more of Mike Thompson's classified filings than his next four subjects combined, and he is ranking member of the tax subcommittee at Ways and Means. Among the bills listed below is one establishing an individual tariff refund credit — a mechanism for returning tariff costs to people through the income tax. Whatever you make of the policy, it is the purest expression of the post: a trade question answered with a tax instrument.

Sponsored bills carry the Congressional Research Service's own subject classification. Mike Thompson's cluster into: Taxation (25), Agriculture and Food (7), Health (4), Public Lands and Natural Resources (4), Emergency Management (2), Armed Forces and National Security (1).

366
Bills sponsored
4412
Bills cosponsored

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

The rest of the list

A measure on military survivors, a bill lowering student loan costs, a cycling act, and one carrying an acronym that reads as a fund-diversion complaint. None of the four is a tax bill, which is the usual pattern here — the aggregate carries the specialism, the recent five carry everything else.

Where he broke ranks

Three yeses the caucus withheld: a main street economic bill, fuel retailing, and a measure on American property held abroad, all of which passed. Two noes against the caucus: a surveillance extension and the consolidated appropriations act, both of which passed as well. Two amendment votes complete the record.
