The choice between Elise Stefanik and Liz Cheney for a House Republican leadership post serves as a proxy war between Donald Trump and Ronald Reagan for the soul of the Party. Reagan and Cheney — and Republicans generally — appear certain to be the losers. For decades after he left office, Ronald Reagan was a glue that united Republicans, just as Franklin D. Roosevelt was for Democrats. Now Trump dominates the Republican Party; Liz Cheney had the audacity to tell the truth: that Trump lost the last election, which many of her House GOP colleagues are too cowardly to acknowledge.
