Bill Cassidy Defeated in Louisiana GOP Primary After Trump Clash
Republican Sen. Bill Cassidy lost his Louisiana Senate seat after a closely watched GOP primary fight that became one of the clearest tests yet of President Donald Trump’s influence inside the Republican Party.
Trump celebrated the outcome shortly after Cassidy’s defeat, marking a major political victory for Trump-backed candidates targeting Republicans who opposed him after the Jan. 6 Capitol attack and 2021 impeachment trial.
Cassidy’s vote to convict Trump became a defining issue throughout the race, with Trump repeatedly criticizing the Louisiana senator publicly and supporting efforts to remove him from office.

The race was also shaped by Louisiana’s new partisan primary system, which political analysts said favored a more ideologically conservative Republican electorate.
Cassidy’s loss is expected to intensify pressure on other Republican incumbents facing Trump-aligned challengers ahead of the 2026 midterm elections.
