Bill Cassidy Loses Louisiana Republican Primary

Bill Cassidy finished third and was eliminated from Louisiana’s Republican Senate primary; Julia Letlow and John Fleming advanced to a runoff. Donald Trump backed Letlow and campaigned against Cassidy. Left-leaning outlets link Cassidy’s defeat to Trump’s campaign against him and Cassidy’s conflicts with the administration. Center outlets mostly treat the result as a test of Trump’s influence, while also reporting the race and, in some coverage, Louisiana election concerns. Right-leaning outlets emphasize Trump’s backing of Letlow as a political win and portray Cassidy’s defeat as a rebuke of his opposition to Trump.
