Why Debate?

Apparently good ol’ Uncle Joe is conscientiously preparing for the final debate, whereas stable genius Trump is blithely ranting at super-spreader rallies. It’s logical, I guess. The general public EXPECTS Biden to manage facts and make sense. No one, however, especially his votaries, has even the remotest expectation that Trump will make sense or utter anything other than whatever addlepated bullshit pops into his head at the moment. The base will roar with approval, even if he does nothing more than belch. And if he shoots himself on Fifth Avenue, well, they will STILL vote for him. So it goes.
