U.S. Representative Julia Letlow celebrated a decisive victory in the Louisiana Republican primary for the U.S. Senate on Saturday night. This result was particularly striking as incumbent Senator Bill Cassidy failed to meet the necessary threshold for a runoff, effectively ending his Senate tenure.
State Treasurer John Fleming finished second, joining Letlow in a runoff set for June 27.
Preliminary results, with a significant portion of votes reported, showed Letlow capturing around 45 percent, Fleming at 28 percent, and Cassidy at 25 percent, while other candidates took the remainder. These tallies positioned Letlow and Fleming as the top candidates under Louisiana’s primary process, which advances the leaders to a runoff when no one achieves a majority.
The November 2026 general election is anticipated to favor the Republican nominee in this staunchly Republican state.
Endorsed by President Donald Trump earlier in the year, Letlow’s strong polling lead and ultimate victory were likely boosted by this support. Representing Louisiana’s 5th Congressional District, she aligned her campaign with the current administration’s initiatives.
The president congratulated Letlow on Truth Social, emphasizing her remarkable victory against an incumbent senator, stating this was unprecedented in primary history. “This is the first time in history that a sitting Senator has lost by such large numbers in a primary, unable to even go forward,” Trump posted.
Letlow is regarded as a promising candidate, with Trump expressing confidence in her potential effectiveness as a senator for Louisiana. He credited his policies for the state’s prosperity and noted his successful election history there.
Following Cassidy’s third-place finish, Trump criticized him for voting to impeach him. “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!” he remarked.
After two terms in the Senate, Cassidy now has no way forward toward re-election. He was one of seven Republican senators to vote for conviction during the Senate trial following the January 6 events.
In response to the election results, Cassidy acknowledged his loss, congratulating Letlow and Fleming while expressing respect for the democratic process.
The upcoming runoff will select the Republican nominee between Letlow and Fleming, with recent polling showing Letlow as the frontrunner, maintaining a lead over Fleming.
Currently, approximately 15 percent of voters remain undecided, which could influence the runoff outcome.
