Incumbent Republican Sen. Bill Cassidy faces a competitive closed-party primary on May 16, 2026, against Rep. Julia Letlow—who leads recent polls at 31% to Cassidy's 21% and former Rep. John Fleming's 25% among likely voters—and potentially a June runoff if no candidate exceeds 50%. Despite this intra-party contest fueled by Trump's January endorsement of Letlow and Cassidy's past impeachment vote against him, traders price a Republican general election victory at 91% implied probability, reflecting Louisiana's deep-red partisan alignment, GOP voter registration edge, and historical precedents where no Democrat has won statewide since 2011. Weak Democratic opposition further solidifies this consensus, though a scandal-plagued GOP nominee, national midterm wave, or legal challenges could narrow the gap ahead of the November 3 contest.
