In hindsight, that press mess with Biden and the Mexico flub seems scripted. He didn't have to go back to the podium, and usually doesn't. And if you see, he referred directly to his notes. I believe we're in the middle of the gradual 'reveal' of biden incompetence in increasing stages of severity, to work on the Dem 'undecided' voters at this point. No way his handlers let him go out there alone unless directed to do so.
