Former President Donald Trump's endorsement of Rep. Julia Letlow in the Louisiana Senate race has failed to deliver the expected boost, with Letlow struggling to gain ground against the incumbent, Sen. Bill Cassidy. Letlow has been massively outspent by Cassidy on advertising, has low name recognition, and faces another candidate with MAGA appeal, making it difficult for her to capitalize on Trump's support.

Why it matters

This race has become a critical test of Trump's political influence, as his approval ratings have reached all-time lows and his ability to remove Republicans who have crossed him, like Cassidy's 2021 impeachment conviction vote, is now in question. The failure of Letlow's campaign to gain traction despite Trump's endorsement could further undermine the former president's standing within the Republican Party.

The details

Letlow's campaign strategy has been criticized as flawed, with her ads focusing almost exclusively on her Trump endorsement rather than attacking Cassidy or defining herself to voters. Meanwhile, Cassidy has gone hard after her on the airwaves. Letlow's other major vulnerability is her geographic distance from the population centers of New Orleans and Baton Rouge, as she hails from a rural district in north Louisiana that is culturally distinct from the Cajun and Creole influence of southern Louisiana.

  • Trump endorsed Letlow in the race in early 2026.
  • The primary election is scheduled for June 2026.

What they’re saying

“The Trump endorsement has not had a close-out move. Cassidy was ready for her. They defined her before she introduced herself.”

— Mike Bayham, GOP state Representative

“We're in the middle of a dogfight. Everyone's expectation is that she would shoot to a large lead and that we'd all be running from behind. But frankly I think they just weren't ready for this race.”

— Mark Harris, Aide to Sen. Bill Cassidy

“People haven't met her. She's almost invisible as a candidate. When you're just meeting someone new in politics, and you hear all these bad things, you might have a first impression, but you tend to start having second thoughts. And he's just relentless in it.”

— Woody Jenkins, East Baton Rouge Parish Chair

What’s next

The primary election is scheduled for June 2026, and the race will be a critical test of Trump's political influence within the Republican Party.

The takeaway

Trump's endorsement has failed to provide the expected boost for his preferred candidate, Rep. Julia Letlow, in the Louisiana Senate race, highlighting the former president's waning influence within the GOP. Letlow's campaign has struggled to gain traction against the well-funded and entrenched incumbent, Sen. Bill Cassidy, raising questions about Trump's ability to remove Republicans who have crossed him.
