Share the canonical public link.
Sen. Bill Cassidy faces a high-stakes Republican primary on May 17, 2026, against Trump-endorsed Rep. Julia Letlow and State Treasurer John Fleming. Cassidy, who voted to convict Trump in 2021, trails in most polls according to RealClearPolitics data. Trump has labeled Cassidy a 'disloyal disaster' and urged voters to support the challengers. Cassidy chairs the Senate Health, Education, Labor and Pensions Committee and raised $5.5 million in cash on hand. Letlow's campaign launched January 20, 2026, and has spent $3.9 million plus $6 million from supporting super PACs.
