Louisiana Rep. Letlow Wins GOP Senate Runoff With Trump Endorsement
A Trump-backed candidate prevailing in a competitive intraparty runoff adds a data point to ongoing assessments of the president's influence over Republican primary outcomes in 2026.
Louisiana Representative Julia Letlow won the Republican Senate runoff election on June 28, 2026, according to an Associated Press projection reported by ABC News. The race was characterized as competitive within the GOP field, and Letlow campaigned prominently on her endorsement from President Donald Trump.
Letlow, who has represented Louisiana's 5th Congressional District, will now advance as the Republican nominee for the U.S. Senate seat. Her campaign strategy centered on the presidential endorsement as a primary closing argument, according to ABC News coverage of the race.
The result continues a pattern in 2026 Republican primaries where Trump-endorsed candidates have advanced in contested intraparty races. The AP projection did not include final vote margin figures at the time of initial reporting; complete certified vote totals will be published by the Louisiana Secretary of State's office once the canvass is complete.
What remains unknown is Letlow's general election opponent, the certified vote margin, and final turnout figures. The Louisiana Secretary of State's certified results and Federal Election Commission post-election filings will provide the definitive financial and vote-total record for this race once filed.
