Republican Julia Letlow won the U.S. Senate race in Louisiana on Nov. 3, defeating Democrat Jamie Davis to replace Sen. Bill Cassidy. Letlow, a U.S. representative, narrowly defeated Davis and will become Louisiana's next senator. She is the first Republican woman elected to the Senate from Louisiana. Letlow will serve a six-year term beginning in January 2027, alongside Republican Sen. John Kennedy.

Letlow will replace Cassidy, who was eliminated in his party's primary earlier this year after seeking a third term. She ousted him in the May closed Republican primary. She won the May 16 primary with 45% of the vote, with State Treasurer John Fleming second at 28%. Letlow then won the June 27 runoff with 56.8% to Fleming's 43.2%, securing the Republican nomination.

Davis is a farmer from Tensas Parish who was a political unknown at the start of the campaign. House Speaker Mike Johnson and Rep. Clay Higgins, both Republicans, will keep their seats in districts 4 and 3, respectively. Nationally, Democrats have won the U.S. Senate and are projected to control the House.
