In Louisiana's closed Republican U.S. Senate primary on May 16, trader consensus heavily favors Rep. Julia Letlow at 66% to secure the nomination, reflecting her endorsements from former President Trump and Gov. Jeff Landry, which have positioned her to consolidate anti-incumbent sentiment against Sen. Bill Cassidy. State Treasurer John Fleming trails at 30% after a recent Emerson College poll showed him narrowly leading Letlow (28%-27%) among likely GOP primary voters, with Cassidy at 21%, yet head-to-head matchups indicate both challengers dominate the incumbent due to his 2021 vote to convict Trump after January 6. Cassidy's attacks on Letlow's past DEI comments and Fleming's surge have tightened the race, but markets anticipate Letlow prevailing outright or in a potential runoff amid strong fundraising and momentum.

If no 2026 Louisiana Republican Senate Primary takes place, this market will resolve to “Other.”
The resolution source for this market will be the first announcement of the results from the Louisiana Republican Party; however an overwhelming consensus of credible reporting may suffice.
