In the humid political landscape of Louisiana, Julia Letlow's decisive runoff victory in late June completed a months-long reckoning within the Republican Party — one that began when Donald Trump turned his endorsement against a sitting senator of his own party. John Cassidy, who had broken with Trump on consequential votes, found that loyalty in today's GOP is not merely preferred but enforced. Letlow's win is less a story about one candidate than about the ongoing consolidation of a political movement that continues to reshape who may speak for the American right.
