One reason that I was pretty bullish on Trump’s chances back when he was still being discounted by a lot of folks was that it seemed so appropriate that Joe Biden would see his crowning political achievement — beating Donald Trump — slip between his fingers and that the supposed great statesman and savior of democracy would be revealed, again, as a middling political hack. I couldn’t have anticipated every particular way Biden would screw it up, but, inevitably, he has, and, for now, even a lot of Democrats are done with him.
