The problem with this reasoning is two-fold. First, Joe Biden is the one that all the world sees trying to shake hands with people not there, who get's lost on stage, and talks about having recent conversations with people long dead. Second, Trump has already repeatedly offered to debate Joe Biden and Biden's handlers have repeatedly ignored this offer.
Again, the problem with this sort of thing is that calling people who can both see and hear what is happening, wrong simply makes them distrust leftist generated 'reasoning' and 'reporting' all the more.
