1/ There's an argument to be made for voting against Trump (meaning, for Biden): a Biden admin will likely kill & hurt less people. I do believe that. But: it's early, & now's the time to push Biden as left as possible. So no point in endorsing now. No one owes Biden their vote.

2/ As for @mehdirhasan, the message isn't landing because his actual aim is to land a hosting gig at MSNBC. That's why he's left-punching and voter-shaming, and that's why he's enough of a Disaster Narcissist to equate himself w/ Bernie, AOC, Chomsky, and Cornel West.
