Louisiana's 2026 cycle is headlined by a U.S. Senate race without its incumbent: Senator Bill Cassidy lost the May 16 Republican primary under the state's new closed primary system, and Representative Julia Letlow faces state Treasurer John Fleming in a June 27 runoff. All six U.S. House seats are also up, shifted to an all-party November 3 primary under a new congressional map after the Supreme Court's Louisiana v. Callais ruling. There is no 2026 governor's race; Louisiana next elects a governor in 2027. Prediction Edge connects live market odds with candidate pages, polling context, official dates and market-moving updates for every tracked Louisiana race.
