Louisiana: Julia Letlow wins GOP Senate runoff | JQJO

BATON ROUGE, Louisiana — Representative Julia Letlow has won the Republican primary runoff for Louisiana’s U.S. Senate seat, defeating State Treasurer John Fleming on Saturday, June 27, 2026, in a closely watched contest that capped an explosive primary season. Letlow, who has represented Louisiana’s 5th Congressional District in the U.S. House of Representatives since 2021, campaigned as a staunch ally of former President Donald Trump and prominently featured his official endorsement. She also highlighted support from Louisiana Governor Jeff Landry and five sitting Republican U.S. senators, using those backing signals to reinforce her standing with conservative voters across the state.

Fleming, a former member of Congress who now serves as Louisiana’s state treasurer, ran a competitive campaign that emphasized his own close ties to Trump, including his service as deputy chief of staff in the Trump White House. He argued that his congressional voting record was more conservative and aligned with grassroots priorities, but voters ultimately coalesced behind Letlow’s message and momentum. Her victory comes after the earlier primary defeat of two-term Republican Senator Bill Cassidy, creating an open seat and marking a significant change in Louisiana’s representation in Washington. Letlow will face Democratic nominee Jamie Davis, a farmer, in the November 3, 2026, general election.
