Assuming your premise is correct, which it's not... Biden would have to have the mental wherewithal to catch Trump in his lies. Which he doesn't.
If Biden debates Trump, expect a lot of short, pre-programmed answers. And in his replies to anything Trump said, expect more short, pre-programmed answers, but off topic in regards to anything Trump said.
I'm not saying this to pick on Biden. I have ultimate respect for those who are my elder. But Joe has no business being the Democrat nominee. He simply is no longer capable, mentally.
