“Bill Cassidy is a sleazebag, a terrible guy, who is BAD FOR LOUISIANA.”
And so began President Donald Trump’s social media rant on Saturday, fresh off his trip to China, back in Washington and waging his revenge tour in full force on a day when fealty to the president is on the ballot in the Bayou State.
“Now he’s going to get CLOBBERED, hopefully, in today’s BIG election, by two great people!!!” the president continued in his Truth Social post, asking GOP voters in Louisiana to cast their ballots for Rep. Julia Letlow, R-La., the candidate Trump is backing to win the high-profile Senate GOP primary contest in a key test of his strength within the Republican Party as he seeks to punish Cassidy for his betrayal.
In his first Truth Social post aimed at Cassidy since returning to U.S. soil, Trump pointed to the two-term senator’s biggest sin: His 2021 vote to convict Trump on impeachment charges related to the Jan. 6 Capitol riots.
“Senator Bill Cassidy of Louisiana is a disloyal disaster. His entire past campaign for the Senate was about ‘TRUMP,’ how he’s with me all the way, and then, after winning, he turned around and voted to IMPEACH me for something that has now proven to be total ‘bullshit!’” Trump wrote.
A third candidate, Louisiana state treasurer John Fleming is also seeking the GOP Senate nomination, and recent polling from Emerson College shows both challengers ahead of Cassidy.
Still, Cassidy has continued to reach out to MAGA voters, saying Friday that the race “is not me versus Donald Trump.”
“If somebody wants someone who can work with President Trump for the good of our country and the good of our state, I’m your candidate,” Cassidy told MS NOW. He did not comment on whether the Republican party has room for those that cross Trump. When asked for comment on the president’s criticism posted Saturday, Cassidy’s campaign responded with a video of Letlow referring to herself as a “progressive leader.”
Cassidy’s battle for political survival illustrates the stark divide within the Republican Party between the establishment and true believers in the MAGA movement.
Richard Logis, a former MAGA activist who defected from Trump’s movement, said Saturday that he believes the MAGA wing of the GOP, which prides itself on being a big-tent party, will continue to splinter as the president’s popularity sinks.
“I do believe that the cracks are there right now,” Logis said on MS NOW’s “The Weekend,” adding, “I think the schisms and the chasms are widening.”

Logis and members of his organization, called Leaving MAGA, are part of a small but vocal community of Republicans mounting an effort to redirect the future of the GOP away from the MAGA movement that Trump created, but their mission faces long odds.
According to polling by YouGov, 63% of Republicans today identify as MAGA, up from 53% in 2025 and 38% back in 2023, a year after Logis left the movement. However, MAGA identification among registered independent voters remains low in the latest polling data — just 12% — and overall, only one in four voters in the U.S. identifies as MAGA.
Trump has spent much of his second term punishing those within his party who broke with his agenda, including a handful of state senators in Indiana who rejected his push to redraw the state’s congressional map. Of the seven state senators who were challenged by Trump-backed candidates, five lost their reelection bids.
The ideological battle within the GOP came into focus early in Trump’s second term. Multiple Republican lawmakers, including onetime MAGA firebrand former Rep. Marjorie Taylor Greene, R-Ga., and Sen. Thom Tillis, R-N.C., either resigned or announced their retirement after breaking with the president.
Greene, who publicly fell out with the president over his ties to Jeffrey Epstein, said in January that “MAGA purity tests and loyalty demands are going to cost the Republican Party votes.” She left Congress after Trump labeled her a “traitor” for criticizing his administration’s handling of the Epstein files and backed a GOP primary challenger in her district.
The president’s pattern of political retribution began in force following his departure from the White House in 2021, when he used his influence to oust prominent GOP incumbents who voted for his impeachment or conviction, including former Rep. Liz Cheney of Wyoming.
On Saturday night in Louisiana after the polls have closed and the counting is done, Cassidy, one of three Republican senators remaining who voted to convict Trump, may find out whether he’s joining Cheney in early retirement.
