On Saturday, Louisiana Republicans will decide whether Donald Trump still runs the GOP's personnel department or whether his endorsement stamp is starting to fade at the edges. The state is holding a Senate runoff between Trump-backed Rep. Julia Letlow and former congressman John Fleming, six weeks after voters already did Trump the favor of kicking impeachment-voter Bill Cassidy out of his own party. Now comes the part where Trump has to actually deliver his chosen replacement.
How We Got Here, Quickly
Bill Cassidy, you may recall, was one of seven Republican senators who voted to convict Donald Trump in his second impeachment trial. That was 2021. Five years is apparently exactly how long a Louisiana Republican voter will hold a grudge, because according to Fox News, Cassidy got just under 25% of the vote in the May primary and became the first elected Republican senator to lose his own party's renomination since Richard Lugar of Indiana in 2012.
Trump, showing all the grace you'd expect, celebrated on social media that Cassidy's 'political career is OVER.' Cassidy, in his concession speech, fired back with a line that landed like a heat-seeking missile: 'When you participate in democracy, sometimes it doesn't turn out the way you want it to. But you don't pout, you don't whine. You don't claim the election was stolen.' He didn't name any names. He didn't have to.
So that part of the story is settled. Cassidy's gone. The question now is who fills his seat, and more specifically, whether that person will be the one Trump picked.
Meet the Two People Actually on the Ballot
Letlow pulled 45% of the vote in the primary, which put her well ahead of Fleming's 28%, but not quite enough to avoid a runoff. She won her congressional seat in 2021 under genuinely tragic circumstances: her husband Luke Letlow died six days after being sworn into the House following his 2020 election win, and she ran for and won his seat. She's been in Congress since, and Trump backed her before she even formally announced her Senate run in January. Louisiana Gov. Jeff Landry, a reliable Trump ally, is also in her corner.
Fleming is not some random spoiler. He spent eight years in Congress and then served as a White House deputy chief of staff during Trump's first term. The man has MAGA credentials. His argument is basically that he's the more conservative candidate, which in a Louisiana Republican primary is saying something. But Trump picked Letlow, and in today's GOP, that's supposed to be the conversation-ender.
Whoever wins the Republican runoff is, per Fox News, the heavy favorite against the Democratic nominee in November. The general election is almost an afterthought in a state this red. The real race is today.
Trump's Recent Endorsement Report Card Is... Complicated
Here's where this gets interesting. Trump's people love to talk about his endorsement record like it's an unbroken string of miracles, and for most of the spring it genuinely was impressive. Fox News reports that Trump-backed candidates knocked off incumbents he'd targeted in Indiana, Kentucky, Texas, and Louisiana's primary. He is very good at aiming his base at people he dislikes and watching them get vaporized.
But the streak has cracks. A few weeks ago in Iowa, Trump made a last-minute endorsement of Rep. Randy Feenstra in the GOP gubernatorial race, and Feenstra lost to Zach Lahn, a businessman and farmer backed by the political wings of the MAHA movement and Turning Point USA. Trump got out-MAGA'd, which is a sentence that should concern him more than it apparently does.
He bounced back in South Carolina, where Lt. Gov. Pam Evette and Lindsey Graham both won their primaries with Trump's backing. Two weeks ago in Georgia and Alabama, Fox News reports his candidates won two of three top races, with the one loss coming against a billionaire who spent over $100 million of his own money. Losing to a nine-figure checkbook is at least an explainable defeat. Losing to MAHA in Iowa is a different kind of warning sign.
Why Georgia Matters More Than Louisiana Right Now
The Louisiana seat is almost certainly staying Republican no matter what. The more consequential recent result in terms of actual Senate math came in Georgia, where Trump's last-minute backing helped Rep. Mike Collins beat former college football coach Derek Dooley in the GOP Senate runoff. Collins will now face Democratic Sen. Jon Ossoff in November, according to Fox News, in what is expected to be one of the handful of races that determines whether Republicans keep their Senate majority.
That's the real game being played beneath all these primary endorsements. Trump is trying to fill the chamber with people who will not, under any circumstances, vote to convict him of anything. The Cassidy situation was a years-delayed punishment. Every primary since has been a lesson delivered to sitting Republicans who might be considering their options.
What a Fleming Win Would Actually Mean
If Fleming pulls off the upset today, it would be the third high-profile endorsement loss for Trump this primary season, which Fox News frames as a meaningful test of his 'immense clout.' That's being polite. Three losses in a season where he started by looking invincible would be a real story.
It would also be awkward because Fleming isn't some anti-Trump rebel. He worked in Trump's White House. He's conservative by any reasonable measure. He just didn't get the blessing, and in the current GOP, that's almost enough to make you the underdog regardless of your actual record. The party has built a loyalty infrastructure so complete that even being a former White House official doesn't protect you if the president decided someone else was his guy first.
Letlow, for her part, told Fox News Digital that Trump's endorsement is 'the most powerful in the world.' Which is exactly what you say when the most powerful endorser in your world is watching.
The Dingo Take
Look, the subtext of every one of these Republican primaries is the same: Donald Trump is methodically converting the United States Senate into a chamber full of people who owe him personally. Not the party. Not the voters. Him. Cassidy voted his conscience on impeachment and spent five years watching his political future rot from the inside. The lesson every other Republican senator has absorbed from that is vivid and not subtle.
The thing about Letlow versus Fleming is that it doesn't even really matter which one wins in terms of governance. Both are going to vote with Trump on essentially everything. The only meaningful difference is that Trump picked one of them, which means a Fleming win would be a small public embarrassment for a president who does not handle small public embarrassments with anything resembling maturity. That's not nothing, but it's also not a policy distinction.
What we're watching in real time is the complete transformation of Republican primaries into loyalty auditions. The issues are largely decorative. The ideology is assumed. The only question that actually moves votes is whether the man in Mar-a-Lago wrote your name on a piece of paper. Bill Cassidy forgot that, briefly, in 2021. Louisiana voters reminded him. Today they'll pick someone guaranteed not to make the same mistake.
