Voting analysis

Bill Cassidy chairs the Senate's health, education and labor committee and sits ex officio on its subcommittees. His departures are amendment votes, and they run in both directions across the aisle.

Supporting one side's amendments, rejecting the other's

He voted for an amendment offered by a Democratic senator that the chamber rejected, and for a libertarian Republican colleague's budget amendment that also failed — while voting against amendments from two other Republicans. A member who backs proposals from both parties and blocks some from his own is not tracking a simple left-right line.

The steadier Louisiana senator

Both Louisiana seats are Republican-held, and the state average is lifted by his colleague. Cassidy departs from the conference less often.

Among the 2 Republicans in the Louisiana delegation, the average rate of voting against the party majority is 8.5%. Bill Cassidy is below that average at 5.9%.

What he legislates on

His filings sit close to his committee's jurisdiction and to his own former profession: the FAIR DME Appeals Act on durable medical equipment, the Outpatient Surgery Access Act, a special education administration measure, and two bills for veterans — one on acquired brain injury caregiving, one on career services for the spouses of veterans lost to suicide.

Sponsored bills carry the Congressional Research Service's own subject classification. Bill Cassidy's cluster into: Armed Forces and National Security (2), Education (1), Families (1), Foreign Trade and International Finance (1), Health (1), Transportation and Public Works (1).

First elected in 2009, now serving across 9 terms. Bill Cassidy falls in the veteran cohort.
