The tension inside the Republican Party is spilling into public view in Louisiana, where Sen. Bill Cassidy is fighting to hold onto his seat while reopening an old wound—his vote to convict Donald Trump in 2021. Now, as he faces a crowded and competitive primary, Cassidy is directing frustration not just at his challengers, but at his own party’s campaign machinery.
According to Punchbowl News, Cassidy recently complained during a phone call that the National Republican Senatorial Committee (NRSC) has not done enough to financially back his reelection effort. The complaint stands out given the scale of resources already behind him. As of January, Cassidy and aligned groups were sitting on roughly $26 million, a sizable war chest for any Senate race, let alone a primary.
The response from inside the NRSC, as reported, was blunt. Executive Director Jennifer DeCasper reportedly pushed back with a profanity-laced reminder of the political reality Cassidy created for himself when he joined Democrats and six other Republicans in voting to convict Trump after the January 6 impeachment trial.
That vote now sits at the center of a primary that has turned into a three-way contest ahead of the May 16 election. Cassidy faces Rep. Julia Letlow and State Treasurer John Fleming, both of whom are working to consolidate conservative voters in a state where Trump remains dominant. Louisiana backed Trump by 24 points in the 2024 presidential election, making his influence in the race difficult to overstate.
Letlow, in particular, has leaned into that alignment, securing Trump’s endorsement. Her campaign has argued that Cassidy’s position is weakening, pointing to polling that in some cases shows him at risk of missing the runoff entirely. One survey cited by her team placed Letlow at 31%, Fleming at 25%, and Cassidy at 21%. Another showed a similar order, again leaving the incumbent outside the top two.
Other data presents a more complicated picture. A Fabrizio, Lee & Associates poll showed a narrow spread, with Letlow at 27%, Cassidy at 26%, and Fleming at 19%, alongside a large bloc of undecided voters. Meanwhile, a poll sponsored by Cassidy’s campaign flipped the standings, placing him at 35%, ahead of Letlow at 24% and Fleming at 21%.
What is consistent across scenarios is the likelihood of a runoff if no candidate clears a majority. Under Louisiana’s updated election system, the top two finishers would advance to a June 27 runoff, setting up a second phase that could reshape the race entirely.
Despite the friction, the NRSC has not abandoned Cassidy. The committee has run ads supporting him, and its chairman, Sen. Tim Scott, has publicly committed to backing incumbent Republicans, even those facing Trump-aligned challengers. Senate Majority Leader John Thune has also endorsed Cassidy and helped raise funds for his campaign.
Still, the political environment remains difficult. Even Scott has acknowledged that incumbents face serious challenges when Trump endorses against them. Cassidy’s situation reflects that dynamic in real time: strong institutional support on one side, and a motivated base aligned with Trump on the other.
Fleming, the third candidate, adds another variable. A former congressman and co-founder of the House Freedom Caucus, he draws from the same conservative lane as Letlow, complicating efforts to consolidate anti-Cassidy voters early.
For now, the race remains unsettled. Some Louisiana Republicans note that Letlow has not yet broken away as a clear frontrunner despite Trump’s backing, suggesting Cassidy’s campaign has managed to blunt her early momentum.
What comes next depends on turnout, late movement among undecided voters, and whether the fractured field narrows before—or after—the first round of voting. In a state where the Republican primary effectively decides the general election, the stakes are contained within the party, but the divisions are fully exposed.
