It comes as no surprise that most Senate Republicans would prostrate themselves for former president Donald Trump even if he were stomping on their knuckles. They voted to acquit not on the merits but because they are scared to death of Trump and his base.
This is a good point, but the larger story of this opinion piece is that a majority of Republicans desires to sacrifice others of their own party to the Trumpistas. This is a losing strategy in the long term, though it may pay short-term dividends.
