About this race
The 2026 United States Senate election in Louisiana will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Louisiana. Republican congresswoman Julia Letlow and Democratic Tensas Parish police juror Jamie Davis are the nominees for their respective parties. The winner will succeed two-term Republican incumbent Bill Cassidy, who was defeated in the primary.
Considered vulnerable to a Republican challenger after he voted to convict President Donald Trump in his second impeachment trial, Cassidy received 24.8% of the vote in the May 16 primary behind Letlow's 44.8% and state treasurer John Fleming's 28.3%. He became the first elected incumbent senator to lose renomination since Richard Lugar in the 2012 Indiana race and one of two to lose renomination in 2026, along with John Cornyn of Texas. Letlow, endorsed by Trump, advanced to a runoff against Fleming on June 27 and won the nomination with 56.9% of the vote. A Democratic runoff between Davis and political consultant Gary Crockett was held the same day, which Davis won with 79.9% of the vote.
With the enactment of House Bill 17 in 2024, the race is the first U.S. Senate election in Louisiana to utilize party primaries instead of a single blanket primary since 2010. Democrats have not won a Senate election in Louisiana since 2008.
