Trump-Backed Pair Advances After Cassidy Primary Defeat

Senator Bill Cassidy of Louisiana lost his Republican primary on Saturday, finishing a distant third as voters turned against the two-term incumbent for his 2021 vote to convict President Donald Trump during his second impeachment trial. With results showing Representative Julia Letlow at roughly 45 percent and state Treasurer John Fleming at 28 percent, Cassidy received about 25 percent and failed to advance. Letlow and Fleming will meet in a June 27 runoff.

The outcome followed a direct campaign by Trump to punish Cassidy for joining six other Senate Republicans in voting to remove the president after the January 6 Capitol riot. Trump had endorsed Letlow months earlier and used social media on election day to label Cassidy a “disloyal disaster” and “sleazebag” who had turned on the man who helped elect him. Cassidy’s defeat marks the latest instance in which Republican primary voters have removed lawmakers who crossed Trump on matters of personal loyalty rather than policy disagreements alone.

Cassidy had tried to shift attention to his record of working with the administration on issues such as health care and infrastructure. Yet the primary results suggest those efforts could not overcome the lingering effects of his impeachment vote. In his concession remarks, Cassidy avoided naming Trump while offering a pointed defense of institutional norms. He told supporters that losing an election does not justify claiming it was stolen or refusing to accept the result, and he stressed that loyalty belongs to the Constitution and the people of Louisiana, not to any single individual.

The race drew limited outside spending compared with other recent contests, yet Trump’s endorsement and repeated attacks appeared sufficient to consolidate support behind Letlow. Fleming, a former Trump administration official, positioned himself as a conservative alternative but could not overtake the president’s preferred candidate. Both finalists have emphasized alignment with Trump’s agenda on issues ranging from immigration enforcement to skepticism of certain federal health initiatives.

Cassidy’s exit continues a pattern in which Republican primaries have functioned as referendums on personal fealty to Trump. Several other senators who voted to convict him chose not to seek reelection in subsequent cycles, leaving Cassidy among the last to test whether a record of institutional independence could survive in today’s party. His loss indicates that voters in deep-red states continue to reward candidates who demonstrate unambiguous alignment with the former president, even years after the events that prompted the break.

The June runoff will now determine which candidate carries the Republican nomination into the general election. Letlow enters as the frontrunner, though Fleming’s respectable showing suggests a segment of the electorate remains open to alternatives that combine Trump alignment with state-level experience. For national Republicans, the result reinforces the incentive structure that favors rapid accommodation to Trump’s priorities over independent judgment on questions of accountability or constitutional process.
