This is bigger than me, so I’ll step aside to beat Trump.
Would pretty much guarantee whoever filled his spot became president.
But moderates demand 100% loyalty. Even if Biden thinks they’re right eventually, he’s not going to change his mind for “the left”. Even when it’s other moderates. He’s been turning on a lot of allies immediately after they even questioned if he should stay in, and claiming CNN and the NY times all sorts of shit despite them backing him all the way up till now.
Biden has never been good at accepting criticism or dealing with confrontation. It’s what torpedoed his first primary back in 88. If someone isn’t with him, Biden considers them against him.
He’s a lot like trump in that regard, loyalty is a one way street.
