Biden's gaffes and footage of him being a creepy weirdo are going to be used against him over and over again. It doesn't matter if Trump has done and continues to do things that are ten times worse every day, that kind of poo just doesn't stick to him at all and pointing out the absurd hypocrisy of it only fires up his death cult even more. There's just far too much ammunition against Biden for him to avoid getting dragged down into the pig poo and having to play the game by Trump's rules.
He'd be a dumpster fire of a candidate, just absolute poo. It isn't 1992 anymore. The only reasons he's considered "electable" are the Obama connection and the fact that he's not on TV making an ass of himself every day yet. He's a horrible mismatch for Trump's debate style too and would get bulldozed and bullied by him all night. None of this is even considering his poo track record as a politician either.
