Well, I'm old enough to remember when Joe Manchin killed the Build Back Better Act, when Barack Obama decided to bailout the banks and not mortgage holders, when Bill Clinton gutted welfare...the party went center-left (debatably center-right on some issues) back in the 90s because they decided that would be a better path to victory. If that's their strategy, fine, but then they aren't entitled to progressive votes.

And again, to his credit, I think Biden has tried harder than all of his predecessors to earn progressive votes: rescheduling marijuana, attempting go cancel student debt, proposing the BBB. He's certainly realized that he can't take progressive turnout for granted, much more than his party has. But Gaza is an albatross around his neck, and it's not the college protesters he needs to be worried about, it's the 300,000 Palestinian-Americans that are about to hand Michigan to Trump.
