On February 13, 2021, Bill Cassidy walked onto the Senate floor and voted to convict Donald Trump for his role in the January 6th attack on the Capitol. He was one of seven Republicans who did. The vote was 57 to 43. It fell short of the two-thirds needed. Trump was acquitted. Cassidy went home to Louisiana.
Five years, three months, and three days later, Louisiana Republicans sent him home for good.
He did not lose to a statesman. He did not lose to a policy argument. He lost to Julia Letlow, a congresswoman from Monroe whose chief qualification in this race was that the president wanted her there, and to John Fleming, a state treasurer who has made his MAGA alignment the centerpiece of his identity since before alignment was the safe bet. The two of them will meet in a runoff. Cassidy will not.
What Cassidy had done, in the interval between that Senate vote and last Friday's primary, was govern. He chaired the Senate Health, Education, Labor and Pensions Committee. He worked the CHIPS and Science Act. He co-authored a bipartisan infrastructure framework. He voted with his party on taxes and judges. None of it was sufficient. The single vote in February 2021 was the only vote that would be counted in Louisiana in May 2026.
The Louisiana Republican Party censured him within hours of the impeachment vote. Not days. Hours. They called it a “betrayal.” Cassidy called it his conscience. He said, in a statement issued the same afternoon, that the evidence was “compelling.” He named the date of the attack. He named the deaths. He said what he saw.
There is a category of political sin that has nothing to do with policy and everything to do with personal loyalty, and in Louisiana on May 16th that category was the only one on the ballot. Letlow did not beat Cassidy on healthcare. Fleming did not beat him on fiscal conservatism. They beat him on the question of whether a Republican senator is permitted to reach a conclusion that embarrasses the president who holds the party's deed.
Cassidy is 58 years old. He is a physician by training. He has represented Louisiana in the Senate since 2015. Before that, he served four terms in the House. He built a career on the ordinary slow work of legislating, which is unglamorous and largely invisible to the people who send you to do it. That career ended last Friday in the kind of result that does not require interpretation.
The two men who stood trial after January 6th and were convicted by juries — not by senators, by citizens — had their records entered into evidence long ago. What Louisiana added to the record on May 16th is simpler: the price of saying so out loud, in a chamber built for exactly that purpose, is your seat.
Cassidy packed his desk at the Russell Building sometime between the vote count and morning.
