Trump-Endorsed Julia Letlow Wins Louisiana Republican Senate Runoff

Published: June 28, 2026, 8:07 am

On June 27, the candidate favored by President Donald Trump secured a decisive win in the Louisiana U.S. Senate runoff election. The result arrived just six weeks after the primary process effectively sidelined Sen. Bill Cassidy’s political career, signaling a continued effort to align the Republican Party with the former president’s platform.

NBC News and Decision Desk HQ projected that Rep. Julia Letlow defeated Louisiana Treasurer John Fleming within 40 minutes of the polls closing. The outcome highlights a significant moment in the 45-year-old congresswoman’s rapid political ascent, which has been substantially bolstered by Trump’s public backing. Letlow first entered Congress in 2021, filling the seat previously held by her husband, Luke, who passed away due to COVID-19 complications shortly before he could take office.

Prior to her congressional service, Letlow was an administrator in higher education and had been considered as a finalist for the presidency of the University of Louisiana at Monroe. Her decision to enter the Senate race followed encouragement from Trump, who targeted Sen. Bill Cassidy due to his vote to convict the former president during the second impeachment trial stemming from the January 6, 2021, U.S. Capitol attack.

In a social media statement posted on January 17, Trump stated, “Should she decide to enter this race, Julia Letlow has my complete and total endorsement.” Beyond the president’s support, Letlow garnered endorsements from several prominent GOP figures, including Louisiana’s House Majority Leader Steve Scalise, as well as Florida Sen. Rick Scott and Alabama Sen. Katie Britt.

Meanwhile, Louisiana Democrats finalized their own nomination by selecting farmer Jamie Davis. Despite this, political forecasters generally categorize the seat as a solid win for the Republican party in the upcoming fall election.
