Louisiana Republican Senate Primary Results in Runoff as Incumbent Cassidy Finishes Third
In the May 16, 2026, Louisiana Republican Senate primary, incumbent Senator Bill Cassidy finished third behind Trump-endorsed Representative Julia Letlow and State Treasurer John Fleming. With no candidate receiving over 50% of the vote, Letlow and Fleming will advance to a June 27 runoff. Cassidy, one of seven GOP senators who voted to convict Donald Trump in his 2021 impeachment trial, faced strong opposition from Trump, who endorsed Letlow and criticized Cassidy as disloyal. Louisiana recently changed its election system from a 'jungle primary' to a closed partisan primary, which some analysts suggest disadvantaged moderate Republicans. The outcome reflects ongoing tensions within the Republican Party over loyalty to Trump and the influence of primary endorsements.
All sources agree on the core outcome: Cassidy lost renomination, finishing third behind Letlow and Fleming. However, framing diverges significantly. Some sources (e.g., The Washington Post) emphasize structural electoral changes, while most (e.g., NBC News, New York Post, CNN) frame it as a referendum on Trump’s control over the GOP. The most complete reports (NBC News, New York Post, USA Today) combine vote data, historical context, and analysis of intra-party dynamics. The least complete (New York Post, The New York Times) either report only pre-results commentary or focus narrowly on Trump’s rhetoric.
