22 OUTLETS
Letlow and Fleming Advance to Louisiana Senate Runoff

Outlets agree that Bill Cassidy lost Louisiana’s Republican Senate primary and Julia Letlow and John Fleming advanced to a runoff. Fleming’s role is to face Letlow in the contest for the Republican nomination. Left-leaning outlets connect the result to Trump’s endorsement and Cassidy’s past impeachment vote, while also noting Cassidy’s criticism of election denial. Center outlets mostly report the result and place it in the context of Trump’s influence, with some also discussing election-process issues or the runoff outlook. Right-leaning outlets more strongly cast Cassidy’s defeat as tied to Trump’s influence and Cassidy’s vote to convict him.
