Bill Cassidy Trails Ahead of May 16 Louisiana Primary as Trump-Backed Rivals Press Challenge
4 articles · Updated · STAT · May 13
May 16 has become a career-defining test for Sen. Bill Cassidy, who faces a bruising Louisiana Republican primary and is running behind in some polls against Rep. Julia Letlow and state Treasurer John Fleming.
Trump’s backing of a challenger and the rise of the Make America Healthy Again movement have sharpened the threat, turning Cassidy’s effort to balance support for the president with occasional breaks from him into a political liability.
Cassidy’s 2021 vote against Trump and his confirmation of Robert F. Kennedy Jr. as health secretary have fueled RINO attacks from the right, while parts of the health policy world see him as abandoning the physician-driven approach that once defined him.
At 68, Cassidy still chairs the Senate committee overseeing health policy, but allies and critics alike say the primary shows how little room remains in today’s GOP for lawmakers who try to straddle Trump loyalty and independent judgment.

The Louisiana Republican Senate primary, as of May 14, 2026, is a highly competitive race with no candidate expected to win an outright majority, making a runoff election likely. Recent polling shows Julia Letlow leading in perceived support for the Trump agenda, followed by John Fleming and incumbent Bill Cassidy. This fragmented support highlights the deep divisions within the party and underscores the importance of Trump loyalty in the race. The runoff will be shaped by undecided voters and the candidates’ alignment with Trump, reflecting broader tensions and shifting dynamics within the Republican Party.
