I don't know if there was a clear cut winner, as it was an embarrassment quite frankly. Wallace sucked as a moderator, Biden scored no points by calling Trump a Clown and telling him to Shut up (even though it was warranted), and anyone that thinks Trump came off looking good must support Fake Bullies that call upon deranged racist white guys to 'stand by' awaiting his commands.
He won't denounce white supremacy, he's trying to actively delegitimize that election, and is calling for violence. He's a complete and utter embarrassment.
If I was the Biden campaign I would not debate again unless they can shut off his mic when it's not his turn.
