Senator Bill Cassidy’s political career effectively ended the night Louisiana Republicans sent a resounding message that voting to convict President Trump has consequences — finishing a distant third in his own party’s primary and watching two Trump-aligned challengers advance to the runoff without him.
Story Snapshot
- Trump-backed Julia Letlow dominated the Louisiana Republican Senate primary with 45.1% of the vote, while Trump-aligned former congressman John Fleming finished second at 28.2%.
- Senator Bill Cassidy, who voted to convict President Trump in his second impeachment trial, finished a distant third with just 24.6% — roughly 80,000 votes behind Letlow.
- Letlow and Fleming advance to a runoff, effectively ending Cassidy’s Senate career as no path forward remains for him.
- Pre-election polling from 270toWin consistently showed Cassidy trailing both challengers, confirming the result was not a surprise but a predictable consequence of his anti-Trump record.
Cassidy’s Impeachment Vote Comes Back to Haunt Him
Bill Cassidy became one of only seven Republican senators to vote to convict President Trump following his second impeachment trial, a decision that defined his political standing in Louisiana ever since. Republican voters in the state never forgave that vote, and the 2026 primary made that verdict official. Cassidy’s 24.6% finish — collecting just 97,073 votes compared to Letlow’s 177,767 — reflects a senator who lost his base by breaking with the president his own party overwhelmingly supported.
PBS NewsHour described the Louisiana contest as “a critical test of Trump’s influence in Louisiana GOP politics,” and the results delivered a clear answer. Trump’s endorsement of Julia Letlow carried enormous weight with the Republican electorate. From the first returns of the night, NBC News data analysis showed Cassidy consistently trailing in third place across most parishes statewide, indicating this was not a close race that slipped away late — it was a structural rejection built over years of frustration with his positioning against the president.
Trump-Backed Letlow Leads Wire to Wire
Julia Letlow, a congresswoman from Louisiana’s fifth district and the candidate carrying President Trump’s endorsement, led the Republican field from the opening returns through the final count. Her 45.1% share of the vote nearly doubled Cassidy’s total, a margin that reflects both the power of Trump’s backing and the enthusiasm of Louisiana’s Republican base. Letlow’s strength was particularly pronounced in her home congressional district parishes, where name recognition and Trump’s endorsement combined to produce commanding margins.
John Fleming, a former congressman and House Freedom Caucus member aligned with Trump, finished second at 28.2%, capturing 111,248 votes. Fleming’s northwest Louisiana base delivered him a solid second-place finish. Notably, the two Trump-aligned candidates together captured more than 73% of the Republican primary vote, leaving Cassidy with little more than a quarter of his own party’s electorate. Pre-election polling from 270toWin had already signaled this outcome, showing Letlow at 34.5% and Fleming at 29.0% against Cassidy’s 20.5% in aggregated surveys leading up to primary day.
What This Means for the GOP and the Runoff
With Letlow and Fleming advancing to the runoff, Louisiana Republicans now face a choice between two candidates who both campaigned in alignment with President Trump’s agenda. Cassidy’s elimination removes from the Senate field the most prominent Republican in the state who had publicly broken with Trump, sending a clear signal to any GOP officeholder tempted to follow a similar path. The Louisiana result reinforces what has become a defining feature of Trump-era Republican primaries: disloyalty to the president carries a steep electoral price.

The runoff between Letlow and Fleming will now determine who takes the seat, but the bigger story from primary night is already written. Louisiana Republicans made their values clear. A senator who voted against the sitting president of his own party, in a state where Trump commands overwhelming loyalty, found no refuge in incumbency, seniority, or name recognition. The base spoke — and it spoke loudly. Whatever the runoff produces, the MAGA movement can point to Louisiana 2026 as proof that accountability in Republican primaries is real and consequential.
