Julia Letlow Advances to Louisiana Senate Runoff

Julia Letlow and John Fleming advanced to a runoff in Louisiana’s Republican Senate primary, while Bill Cassidy finished third and did not advance. Letlow had President Trump’s endorsement. Center outlets emphasize the result and often present the race as a test of Trump’s influence, with Cassidy’s impeachment vote as context. Right-leaning outlets also stress Trump’s role but more often cast Cassidy’s loss as payback for that vote.
