Bill Cassidy Finishes Third in Louisiana Republican Primary

Donald Trump backed Julia Letlow and opposed Bill Cassidy, who finished third in Louisiana’s Republican Senate primary as Letlow and John Fleming advanced to a runoff. Left-leaning outlets portray the defeat as part of Trump’s effort to remove Republicans who oppose him. Center outlets also connect the result to Trump’s pressure on GOP critics, but emphasize what it shows about his influence over the party. Right-leaning outlets mostly present the result as a win for Trump over Cassidy, with one linking it to Cassidy’s impeachment vote and another crediting Trump’s political influence.
