Louisiana Republican Julia Letlow secured her party’s U.S. Senate nomination Saturday, defeating former state treasurer John Fleming with 57% of the vote in a runoff shaped heavily by a Donald Trump endorsement. On the Democratic side, Jamie Davis claimed his party’s nomination with a commanding 80% of the vote, becoming the first Black candidate to advance to a Louisiana U.S. Senate general election since Reconstruction.
Why It Matters
The November matchup between Letlow and Davis will be one of the most closely watched Senate contests in the South this cycle. Louisiana gave Trump more than 60% support in 2024, giving Letlow a structural advantage heading into the general election. Davis’s historic nomination adds a significant dimension to the race and the state’s political landscape.
The contest also marks the first Louisiana Senate election held under a new party-primary system, replacing the “jungle primary” format the state had used for roughly 50 years. Under the new rules, no-party voters were required to choose a major-party ballot in May and remain with that party through Saturday’s runoff, though November’s general election will be open to all voters.
What Happened
Letlow, who has represented Louisiana’s 5th Congressional District since 2021, received Trump’s endorsement in January — notably before she had even formally announced her candidacy. The Associated Press called the Republican race for Letlow just 45 minutes after polls closed. Gov. Jeff Landry also backed Letlow, a combination of support that Fleming said worked against him.
Fleming, elected state treasurer in 2023 and a former 4th Congressional District congressman from 2009 to 2016, held three roles in Trump’s first administration but was unable to convert that résumé into a winning coalition. He accused Landry of blocking his access to Trump during the campaign. Fleming, who turns 75 on July 5, acknowledged the outcome graciously. “It didn’t turn out as we had hoped, and you know, that that’s OK,” he said. “This is a very healthy process.”
Letlow credited Trump’s backing as decisive. “His endorsement is really the most powerful endorsement in the world,” she said of her working relationship with the president.
On the Democratic side, Davis — a third-generation crop farmer from Tensas Parish and former Tensas Parish Police Jury member — dominated the runoff after narrowly advancing from the May primary. He had received 47% in that earlier contest, while his runoff opponent, Orleans Gary Crockett, had edged into the runoff by fewer than 300 votes over a third candidate, Nick Albares. Davis captured 79% of votes cast in New Orleans on Saturday, with fewer than 90 of the city’s 349 precincts still uncounted at the time of reporting.
By the Numbers
57% — Letlow’s share of the Republican runoff vote.
80% — Davis’s share of the Democratic runoff vote.
45 minutes — Time between poll closing and the AP’s call for Letlow.
60%+ — Trump’s 2024 vote share in Louisiana, illustrating the Republican lean of the state.
50 years — How long Louisiana used the jungle primary format before switching to the current system.
Zoom Out
Louisiana’s Senate race reflects a broader national pattern in which Trump endorsements continue to carry decisive weight in Republican primaries. Fleming’s deep ties to the Trump administration were not enough to overcome Letlow’s direct endorsement from the president himself. The state’s new primary structure may also influence future electoral dynamics, as parties now exercise more control over who advances to a general election. Louisiana lawmakers closed their most recent legislative session with several contested priorities unresolved, adding to the political environment heading into November.
What’s Next
Letlow and Davis will face each other in the November general election, which will also include six U.S. House races. Those House contests were originally scheduled for May 16 primaries before Gov. Landry issued an executive order postponing them. The U.S. Supreme Court’s decision in Callais v. Louisiana, which concerned the state’s 6th Congressional District, adds a further legal dimension to the fall ballot. Fleming’s part-time consulting work for The McKeon Group while serving as treasurer drew scrutiny during the campaign but did not alter the race’s outcome.
