John Fleming, the state treasurer and a former Trump administration official, edged out Mr. Cassidy to finish second, with about 28 percent of the vote.Both Ms. Letlow and Mr. Fleming will advance to a runoff on June 27, according to The Associated Press.Neither secured a majority of votes. But Mr. Cassidy, who voted to remove Mr. Trump in 2021 for inciting insurrection and has clashed with the Make America Healthy Again movement over vaccines, could not even secure enough support in his state to stay in the race, finishing with around 25 percent of the vote.After the race was called, Mr. Trump celebrated in a social media post, writing that Mr. Cassidy’s “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!”Mr. Cassidy’s defeat was the latest victory in Mr. Trump’s campaign of political retribution against Republicans who have defied him. This month, the president and his political operation successfully backed challengers to Indiana lawmakers who rejected his demands on redistricting. On Tuesday, he will try to unseat Representative Thomas Massie, a Kentucky libertarian who is Mr. Trump’s most vocal Republican critic in the House.Even as a two-term incumbent with a powerful committee chairmanship and millions of dollars in his campaign war chest, Mr. Cassidy was not able to overcome attacks from Mr. Trump and others in his party.In his concession speech, Mr. Cassidy, who shied away from directly criticizing the president while running for re-election, took thinly veiled swipes at Mr. Trump and his repeated false claims of election rigging.“When you participate in democracy, sometimes it doesn’t turn out the way you want it to,” he told dozens of supporters in Baton Rouge. “But you don’t pout. You don’t whine. You don’t claim that an election was stolen from you.”Without naming Mr. Trump, Mr. Cassidy expressed his view that America’s leaders should be focused not on “one individual” who demanded absolute loyalty but rather on the general welfare of the public.“And if someone doesn’t understand that and attempts to control others through using the levers of power, they’re about serving themselves,” he said. “They’re not about serving us. And that person is not qualified to be a leader.”Mr. Cassidy’s impeachment vote opened what turned out to be an irreparable rupture between the president and Mr. Cassidy, which extended to many of his constituents back home. The state Republican Party censured him, and Mr. Trump has spent the years since blasting Mr. Cassidy and vowing to oust him.Mr. Cassidy took steps to try and repair his relationship with the president, and his voting record during Mr. Trump’s second term has hewed largely to Mr. Trump’s priorities.In a notable attempt at rapprochement, Mr. Cassidy, a gastroenterologist and strong proponent of vaccines who leads the Senate health committee, reluctantly backed Mr. Trump’s choice for health secretary, the vaccine skeptic Robert F. Kennedy Jr.But the move failed to quell Mr. Trump’s anger, and the uneasy embrace did not create a lasting alliance between Mr. Cassidy and Mr. Kennedy, who draws support from a powerful movement that has become a potent piece of Mr. Trump’s coalition and invested heavily in beating Mr. Cassidy.Mr. Cassidy’s decision on Mr. Kennedy also may have cost him crucial support with independent voters and centrists who might otherwise have crossed party lines to vote for him. Louisiana had also changed its election law to hold closed primaries, diminishing Mr. Cassidy’s potential base of support.The change was championed by Gov. Jeff Landry, a Republican who endorsed Ms. Letlow. Mr. Cassidy’s campaign accused him of engineering it to benefit her.Mr. Cassidy’s replacement will most likely contribute to the further consolidation of Senate Republicans behind Mr. Trump and his agenda. Only two other G.O.P. senators who voted to convict the president in 2021 remain in office: Lisa Murkowski of Alaska and Susan Collins of Maine, who is facing a tough re-election battle.Ms. Letlow heads into the Louisiana runoff buoyed by the backing of the president and the governor and her first-place finish.In her victory speech, she thanked Mr. Trump, saying Saturday’s results reflected the power of his endorsement. “Tonight, Louisiana sends a clear message,” she said, adding: “They want a candidate to represent them in the Senate who will always put America first and never turn her back on Louisiana voters.”Ms. Letlow, a three-term congresswoman from relatively rural northeast Louisiana, had trained attacks in the last month of the race on Mr. Fleming, who may be a tougher opponent than Mr. Cassidy.As Mr. Cassidy sought to keep his political career alive, his campaign and groups supporting him spent more than $21 million on ads, many of them attacking Ms. Letlow as overly liberal. In recent weeks, he highlighted a video in which she voiced support for diversity, equity and inclusion initiatives as she was interviewing for a job as a university president.Mr. Fleming seized on those statements as he tried to cut into Ms. Letlow’s support with voters loyal to Mr. Trump by arguing that he is more closely aligned with the president.Mr. Fleming spent eight years in Congress, leaving in 2017. He later was a White House deputy chief of staff in the final months of Mr. Trump’s first term, including in the weeks after the Jan. 6 attack.
