55 OUTLETS
Bill Cassidy Finishes Third in Louisiana Republican Senate Primary

Outlets agree that Bill Cassidy finished third in Louisiana’s Republican Senate primary and will not advance, while Julia Letlow and John Fleming advance to a runoff. Left-leaning outlets frame the result mainly as part of Trump’s effort to oust Republicans who opposed him, often noting Cassidy’s criticism in his concession. Center outlets largely treat it as a test of Trump’s influence and report both his celebration and Cassidy’s response. Right-leaning outlets stress Cassidy’s break with Trump or voters’ rejection of his record, while some portray the result as evidence Trump’s endorsement still carries weight.
