Louisiana Senate Runoff Recap: Letlow Cashes the Chalk, Davis Wins the Democratic Nod
- The betting favorites delivered in Louisiana. Trump-backed Rep. Julia Letlow won Saturday's Republican Senate runoff with about 57% of the vote, cashing a position the markets had priced near 87%.
- The late "Fleming is closing" story never reached the scoreboard. Despite polls suggesting a tightening race, Letlow beat state Treasurer John Fleming by roughly 14 points, and the 13-cent long shot on Fleming busted.
- Democrats picked Jamie Davis, a Tensas Parish farmer, who rolled to about 80% over Gary Crockett after leading every parish.
- The result sets a November race the markets see as all but decided. Louisiana has not elected a Democrat to the Senate since 2008, and the Republican is near 92% to hold the seat.
- After Colorado humbled the favorites, Louisiana was a clean night for the chalk, though the payouts were thin.
BATON ROUGE - Two nights after Colorado torched the betting favorites, Louisiana handed them back the wheel. Rep. Julia Letlow, the Trump-endorsed front-runner the markets had loved all along, won Saturday's Republican Senate runoff comfortably, and on the Democratic side the party's establishment pick rolled. There was a late scare in the coverage, a run of polls suggesting Treasurer John Fleming was closing fast, but the ballots said otherwise. In a runoff the markets had all but priced as over, it was over.
Letlow Cashes as the Favorite
Letlow entered Saturday as roughly an 87% favorite on Polymarket, and she validated the price. She won the nomination with about 57% of the vote to Fleming's 43%, a 14-point margin that looked nothing like the nail-biter some late surveys advertised. It was the kind of night that pays the chalk: a Yes share on Letlow at about 87 cents returned a dollar, a small profit for backing the obvious, while Fleming's roughly 13-cent ticket expired at zero.
Letlow's win completes a takeover that began in January, when President Trump endorsed her before she had even formally entered, and it caps a race in which she nearly won the May primary outright with 45%. She thanked Trump from the stage, and he congratulated her online soon after. With the win, Letlow became the fourth Trump-endorsed Senate candidate to take a party runoff this year, another data point for a market that keeps pricing his endorsement as close to decisive in Republican primaries.
The Fleming Path That Never Opened
The one thing that could have made this interesting was a genuine Fleming surge, and for a few days the market had a reason to sweat it. Fleming, a self-funded former congressman running hard to Letlow's right, released internal polling showing the gap tightening, and at least one independent survey framed the runoff as competitive. That is the setup that tempts underdog bettors: a 13-cent price on a candidate with a plausible story.
It did not hold up. Letlow's coalition, powered by Trump and Gov. Jeff Landry and a wave of allied ad spending, turned out, and the "path" closed. Fleming had poured more than $11 million into the race, much of it his own money, and still lost by 14 points. For anyone who took him looking for a longshot payday, the lesson was familiar: a tightening narrative is not the same as a tightening result, and a big checkbook does not buy one either.
Davis Runs Away With the Democratic Nod
The Democratic runoff was never in doubt, and it played to form. Jamie Davis, a row-crop farmer and former Tensas Parish official backed by the state party, beat New Orleans businessman Gary Crockett with about 80% of the vote, roughly 157,000 to 39,000, and carried all 64 parishes. Davis had nearly clinched the nomination outright in May with 47%, and his cash and organizational edge made the runoff a formality.
His win carried history with it. By his own account on election night, Davis is the first Black candidate Louisiana has nominated for the U.S. Senate since Reconstruction, and he invoked P.B.S. Pinchback, the Reconstruction-era Louisiana figure who was elected to the Senate but never seated. The catch is what comes next, a general election in which he starts as a heavy underdog.
Cassidy's Fall, in the Rearview
The whole runoff traced back to an incumbent who never made it this far. Sen. Bill Cassidy finished third in the May primary and became the first elected Republican senator to lose renomination since 2012, a casualty of his 2021 vote to convict Trump. Trump publicly celebrated the defeat, and Cassidy, conceding, offered a dry line about democracy not always breaking your way. The markets had written him off well before the votes were counted, and Saturday closed the book.
November Is a Near-Lock on the Board
For the fall, the Senate betting odds barely register a contest. Louisiana has not sent a Democrat to the Senate since 2008, and the Republican nominee sits near 92% to hold the seat. That makes Letlow the overwhelming favorite over Davis in November, and it is why the runoff, not the general, was always the real decision. On the wider Louisiana political odds, this seat is about as close to settled as an unvoted race gets.
The Payout Read
For a market audience, Louisiana was the anti-Colorado: on a sleepy runoff turnout of roughly 17% of registered voters, the favorites won, but they did not pay much. Letlow at 87 cents and Davis near 80 cents were both chalk, and both came in. The only real value on the board was the Fleming longshot, and it lost. One reminder that cuts both ways: these are win prices, not vote shares, so an 87-cent favorite hands you only pennies of profit, while the risk always sat with the 13-cent side that never arrived. Some nights the boring bet is the right one.
What Comes Next
Louisiana now has its November matchup set, Letlow versus Davis, with the Republican a prohibitive favorite to keep Cassidy's old seat in the party's hands. Davis will campaign as a historic nominee facing long odds, and Letlow will run as the front-runner she has been since winter. For the latest election odds, the Louisiana Senate race is effectively priced for the fall, and the surprises, such as they were, ended in the primary.
