- Bill Cassidy's February 2021 impeachment conviction vote — one of 7 Republican senators to convict Trump — resulted in an 83-17 censure from Louisiana Republicans within 10 days.
- The censure vote is the decisive primary data point: 83% opposition from your own party's state organization typically signals a primary challenge that cannot be survived in a deep-red state.
- Cassidy has largely maintained his conviction stance rather than walking it back, calculating that the general election is safe enough (Safe R) to absorb a primary loss to a MAGA candidate.
- The seven conviction senators represent a natural experiment in Republican politics: some survived (Collins, Murkowski), some lost primaries (Cheney in House), and some retired rather than face voters.
- Louisiana's jungle primary system means Cassidy could be eliminated before the general election by a MAGA challenger — the general election's Safe R status is irrelevant if he doesn't make it there.
The Impeachment Vote and Its Lasting Shadow
On February 13, 2021, Bill Cassidy was one of seven Republican senators to vote to convict Donald Trump in the second impeachment trial over the January 6 Capitol attack. The Senate fell short of the two-thirds threshold needed to convict, with 57 voting guilty and 43 voting not guilty. Cassidy's vote was notable: just days earlier he had voted with most Republicans to dismiss the trial on procedural grounds, then changed his position after viewing the House managers' evidence presentation. He said Trump was "guilty of a terrible act" and that "the evidence is compelling."
The Louisiana Republican Party responded within 48 hours, censuring Cassidy 37-to-23 in an emergency meeting. The speed and margin of the censure illustrated how thoroughly Trumpism had consolidated the Louisiana GOP. Cassidy was unbowed publicly, calling the censure "expected" and saying he voted his conscience. But politically, the vote created a durable wound that has not healed in the five years since.
The Seven Conviction Senators: What Happened Next
Trump's Endorsement Calculus
Trump's track record on revenge primaries is mixed: he primaried Liz Cheney successfully (she lost in Wyoming 2022) and failed to unseat Murkowski (she won in Alaska via ranked-choice). Louisiana's jungle primary system complicates the calculus — a fractured Republican field could theoretically allow a Democrat into a runoff, which Trump wants to avoid. Expect a Trump endorsement of a challenger only if a strong, well-funded primary candidate emerges with clear path to the runoff.
Cassidy's Senate Record Post-Vote
Since 2021, Cassidy has largely returned to mainstream Republican voting, supporting most GOP priorities on taxes, energy, and regulatory rollback. He chairs the Senate HELP Committee's health subcommittee and has worked on bipartisan infrastructure and pension reform. His substantive record may help him in a general election but does little to neutralize primary anger from base voters who view the conviction vote as an unforgivable betrayal.
Louisiana Jungle Primary: Wild Card
Louisiana holds all-party primaries on Election Day. If no candidate crosses 50%, the top two advance to a December runoff regardless of party. In a multi-candidate Republican field, Cassidy could potentially make the runoff on name recognition and incumbency even with depressed base support — then face either a fellow Republican or, in a worst case for Louisiana Republicans, a Democrat. The format reduces but does not eliminate primary risk.
Frequently Asked Questions
Why is Cassidy's 2021 vote still politically relevant in 2026?
Louisiana Republican primary voters are among the most Trump-aligned in the country. The state party's immediate censure vote showed the depth of feeling. Five years later, Republican base voters in Louisiana have not moved on — and Trump's continued political dominance means the conviction vote remains the defining frame for any Cassidy primary challenge.
Could a Democrat win Louisiana in 2026?
Virtually no forecaster rates this as possible under current conditions. Louisiana has not sent a Democrat to the Senate since Mary Landrieu's 2014 loss. Trump\'s approval the state by 20+ points in 2024. The seat is Safe Republican in the general regardless of who wins the Republican primary.
What is Cassidy's path to survival?
Cassidy's best outcome requires either no strong well-funded challenger entering, or the jungle primary splitting anti-Cassidy votes among multiple Trump-aligned candidates while he consolidates moderate and business-Republican support. His incumbency advantage, fundraising capacity, and statewide name recognition all help — but none override the fundamental problem of running in a Trump+20 state after voting to convict Trump.
