The fury at Jon Stewart is kind of funny because we're talking about one of the most basic normie center-left liberal celebrities in the country, and he's certainly not without his failings, but he hasn't really changed. It's Biden who has tacked right and failed to quell Trump's fascist movement while insisting he alone can fix it.
And I should qualify that Biden hasn't really tacked right so much as he's always been a mediocre conservative Democrat with a vocal antipathy toward abortion rights and Palestinians. He hasn't got a selling point for his candidacy beyond rehashing his fight with Trump ad nauseam, and he and his boosters simply feel entitled to votes while telling people to go fuck themselves if they expect better.
What the fuck are we doing, indeed.
