This is the guy who said that his new strategy is to go for Trump's jugular.
More bad info from his team. I think they figure that by doing the same kind of name calling that Trump does, they will rattle him. I guess they sort of will, but Trump's response to that stuff is to double down on return volleys, and without a script, Biden is going to look pretty dumb when he freezes up at their first debate after Trump goes mean girl on him.
