I don’t even know who I would bet on. Trump can’t use stairs and Biden seems more active but he’s at that age where you’re one fall away from a broken hip and becoming bedridden.
Why do that when we can intentionally lead them slightly over the border, void their citizenship, and then tell them they have to sit in a detention center until they can be processed.
As fun as that would be, the fight wouldn't last more than a couple minutes. Trump would just need to knock over elderly Biden and sit on him with his fat ass until Biden surrenders.
Biden gets on his bike and rides on a regular basis, dude in his 80's, but he's more active than most people his age. Not that "who can win in a fight" is really a good metric for anything, but framing Biden as a doddering old man is just plain false.
I don't pay enough attention to politicians to know anything positive about them. If he actually does do rides and keeps active, then damn! Good for him.
