You know how Biden could win the election? During the debates, have one of the questions be a "plant" by one of the questioners. The question: "Mr. Trump and President Biden, Americans consistently say that one of their chief concerns about this election is your ages. Both of you contend that you are fitter than your opponent. Knowing that an inability to stand still is one of the early-warning signs of dementia, will both of you would step out from behind the podium, stand next to one another, close your eyes, and stand there without touching or holding on to anything for 30 seconds?"
Biden, knowing the question is coming, would have practiced. Plus he'll have taken half a valium. Trump will panic, knowing that he can't do it. He'll either have to decline to do it, at which point everybody says "what's the big manly man so afraid of?" or he'll have to do it and his dementia unsteadiness will be exaggerated by his nervousness. He'll be swaying like I used to coming out of Maggie Mae's at two a.m.
