It was a hurdle too high for Bill Cassidy to clear. The Republican senator from Louisiana had tried to satisfy Donald Trump and his supporters, but they couldn't forgive him after he voted to convict at the president's impeachment trial over the Jan. 6 riot at the U.S. Capitol. That was more than five years ago and the ill will lingered. Trump backed one of Cassidy's challengers in Saturday's Senate primary, and the incumbent finished third. He didn't even make the June runoff. Cassidy is the latest name on an increasingly long list of Republicans who crossed Trump and were punished by voters.
