Cassidy Draws Primary Challengers 

 BATON ROUGE, La. — Louisiana’s 2026 U.S. Senate race is accelerating into a marquee Republican primary, with incumbent Sen. Bill Cassidy facing a growing field of challengers ahead of the state’s newly restored partisan primary elections. 

Among the Republicans seeking the seat is Louisiana State Treasurer John Fleming, a physician, military veteran, and former U.S. congressman who has positioned his candidacy around fiscal stewardship and a hardline conservative approach to federal policy. Fleming, who has served as treasurer since January 2024, argues that Louisiana needs a senator aligned with the party’s base and focused on spending restraint, border enforcement, and expanding domestic energy production.
