The towel should be thrown in

Joe Biden won't cancel himself from the debates, he's too much of an old stager. He's been doing this all his life or at least he seems to have been around in politics for ever. He most likely doesn't know what shape he's in and that he's making all the speech & thought errors that he is.
I don't know if many people ever saw Anthony Quinn in Requiem for a Heavyweight but that will be Joe Biden getting in the ring with Donald Trump. I wouldn't, I don't think anyone would want to see that.
Not that I think Trump would want to exploit it, it's just that it would be inevitable.
