Louisiana Election Results
Bill Cassidy Loses Primary as Letlow and Fleming Head to Runoff
Published: May 17, 2026
The Louisiana election results from Saturday, May 16, sent shockwaves through Washington: Senator Bill Cassidy, a two-term Republican incumbent, has been eliminated from his own party’s primary. The Louisiana primary results show Rep. Julia Letlow — backed by President Donald Trump — leading the field, with State Treasurer John Fleming securing the second runoff spot. The two will square off on June 27 to determine who becomes Louisiana’s next Republican Senate nominee.
For anyone following the Louisiana senate race, this outcome was months in the making. But seeing it confirmed in the election results louisiana voters delivered Saturday night still marks a remarkable political moment — one that reveals just how completely Trump has reshaped the Republican Party.
Louisiana Primary Results at a Glance
When the votes came in Saturday night, the Louisiana primary results were decisive. With the majority of ballots counted:
- Julia Letlow: ~44–45% of the vote
- John Fleming: ~28% of the vote
- Bill Cassidy: ~25% of the vote
- Mark Spencer: ~2% of the vote
Because no candidate cleared the majority threshold required to win outright, the top two finishers advance to a runoff. Louisiana voting rules require a candidate to win more than 50% of the vote to avoid a second round — a bar that Letlow, despite her commanding lead, fell short of on primary night.
The June 27 runoff will pit Letlow against Fleming in what is expected to be a fierce contest over who is the more loyal Trump ally.
What Happened to Bill Cassidy?
Senator Bill Cassidy’s fall from grace in Louisiana politics traces back to a single vote: on February 13, 2021, Cassidy became one of just seven Republican senators to vote to convict Donald Trump following the January 6 Capitol riot. It was a vote of conscience — and it cost him nearly everything politically.
From that moment forward, Sen. Bill Cassidy was living on borrowed time in ruby-red Louisiana. The Louisiana Republican Party censured him within days of the impeachment vote. Trump never forgot. And when the Louisiana senate race came around in 2026, Trump made clear that Cassidy’s political career had an expiration date.
“His disloyalty to the man who got him elected is now a part of legend, and it’s nice to see that his political career is OVER!” Trump wrote on Truth Social following the Louisiana election results Saturday night.
Senator Cassidy, a physician from Baton Rouge, was first elected to the Senate in 2014 after previously serving in the U.S. House and the Louisiana State Senate. He sought a third term this cycle, arguing on the campaign trail that he maintained a productive working relationship with the president despite their differences. “I’m not claiming the president loves me — no — but you can work with people even if you don’t love each other if you’ve got a common goal,” Cassidy said on CNN the day before the Louisiana primary.
It wasn’t enough. The bill cassidy louisiana election results made clear that in today’s GOP, a vote to convict Trump is effectively a career-ending act.
The Role of Trump’s Endorsement
The Trump factor loomed enormous over this louisiana senate primary. In January 2026, Trump threw his full support behind Julia Letlow, a congresswoman from northeastern Louisiana and the widow of late Rep. Luke Letlow. The endorsement gave her campaign an immediate infusion of energy, fundraising, and credibility with the MAGA base.
Trump’s involvement in the bill cassidy trump feud was deeply personal. Beyond the impeachment vote, Cassidy clashed with the Trump administration repeatedly in his role as chairman of the Senate Health, Education, Labor and Pensions (HELP) Committee. He expressed reservations about RFK Jr.’s nomination as Health Secretary. He split with the White House on vaccine policy. And when Trump’s surgeon general nominee Casey Means had to be pulled, Trump publicly blamed Cassidy — calling him “a very disloyal person” in a Truth Social post.
That accumulated friction meant Trump wasn’t just passively rooting against Cassidy — he was actively campaigning for his defeat in the louisiana election.
Adding another layer to the cassidy louisiana story: Governor Jeff Landry, a Trump ally, pushed through a change to Louisiana’s voting system, switching from an all-party primary (sometimes called a “jungle primary”) to a partisan primary format. That structural change favored Trump loyalists, since Republican base voters — the most enthusiastic Trump supporters — would make up a larger share of the primary electorate.
Who Is Julia Letlow?
Julia Letlow emerged as the clear frontrunner in the louisiana senate primary, buoyed by Trump’s endorsement and the backing of Governor Landry. She entered the Louisiana senate race with strong name recognition from her own congressional career and the legacy of her late husband.
Her campaign painted Letlow as a reliable MAGA ally who would stand with Trump in the Senate. She raised substantial funds, dominated polling, and — as the election results louisiana showed — turned that support into real votes.
Letlow won’t be the senator just yet. She still has to win the June 27 runoff. But with Trump in her corner and nearly 45% of the primary vote already, she enters that contest as a strong favorite.
Who Is John Fleming?
John Fleming is no newcomer to louisiana politics. A former congressman who represented northwestern Louisiana, Fleming spent time working in the Trump White House during the president’s first term — a credential he has wielded prominently throughout this louisiana senate race.
Fleming’s campaign framing was essentially: I’m the real Trump loyalist in this race. His team attacked Letlow as a “Never Trumper” (a charge her campaign rejected aggressively) and targeted her on other issues, including her work as a lobbyist prior to becoming State Treasurer.
The john fleming louisiana primary strategy succeeded enough to land him in the runoff, though he trails Letlow by a significant margin. Between now and June 27, Fleming will need to consolidate support among conservative voters skeptical of Letlow and make a convincing case that he’s the more proven Trump ally.
Cassidy’s Concession: A Final Word
In his concession speech Saturday night, sen bill cassidy did not name Trump directly — but observers noted clear references to the president in his remarks. Cassidy appeared to push back against what he saw as a punitive political culture, without publicly relitigating the impeachment vote that defined his final term.
Cassidy will become the first Republican senator to lose a regular primary election since 2012 — a remarkable footnote in American political history. His defeat is also notable in that it completes a kind of political accounting: nearly every Republican who voted to convict Trump in 2021 has now either lost a primary, retired rather than face one, or left office under pressure.
What the Louisiana Voting Results Mean for the GOP
The louisiana primary results are more than a state story. They are a referendum on dissent within the Republican Party — and dissent lost.
Trump has now demonstrated, clearly and repeatedly, that he can reach into states and remove Republicans who crossed him. With Cassidy’s loss confirmed by the election results louisiana voters delivered, the message to every remaining Republican in Congress is stark: disloyalty to Trump carries a steep price.
It also means Louisiana is on track to elect a senator who will be deeply aligned with the White House. In a state Trump has carried six consecutive times — including primaries — the Democratic nominee in November faces an enormous uphill battle regardless of who wins the June 27 runoff between Letlow and Fleming.
On the Democratic side, louisiana voting also produced a runoff: Jamie Davis and Gary Crockett will face each other after neither secured a majority in the Democratic primary.
What Comes Next: The June 27 Runoff
The louisiana senate race is not over. Here’s what to watch heading into the runoff:
- Will Trump stay with Letlow? Trump congratulated Letlow on Saturday night, calling her a “fantastic person” and a “spectacular” future senator. Barring a major shift, his support appears locked in.
- Can Fleming close the gap? He trails by roughly 16 points. That’s a large deficit, but runoff electorates are smaller and more unpredictable.
- How does the Letlow-Fleming battle over Trump loyalty play out? Expect both campaigns to aggressively position themselves as the president’s true champion in the Senate.
- What is Cassidy’s role, if any? Cassidy has not endorsed either runoff candidate. His approximately 25% of primary votes could matter on the margins.
The winner of the June 27 republican primary will be the overwhelming favorite in the fall general election, making that runoff effectively the final decision for Louisiana’s next U.S. senator.
Final Thoughts on the Louisiana Election Results
The louisiana election results of May 16, 2026, close a significant chapter in American Senate history. Senator Bill Cassidy — a physician, a policy wonk, and one of the few Republicans willing to break with Trump on the most consequential vote of the modern era — has been shown the door by his own party’s voters.
The bill cassidy louisiana primary outcome will be studied for years as a case study in how far Trump’s influence over the GOP extends, and how high the cost of conscience can be in today’s political environment.
With Letlow and Fleming headed to a June 27 runoff, the louisiana senate race enters its final chapter. One of them will become Louisiana’s next senator. Both have made clear they intend to govern as loyal Trump Republicans.
The era of the independent-minded louisiana senator, embodied in Cassidy’s complicated legacy, appears to be over.
