IMO, the people behind Biden will give him whatever medication possible to make him as alert as they safely can. He won’t appear to be the wandering fool he was at the G-7 meetings earlier this week.
The tactics Trump should employ is to turn everything back onto Biden and LET HIM SPEAK, the more the talks the more he will lie and misstate obvious facts, Biden is his own worst enemy, let him bury himself.
Biden will have canned answers, he will know beforehand what the questions will be, when Trump responds, get him off the prepared answers, bring up the laptop bring up everything regardless of what the question is, turn it back onto Biden and badger him and make him think on his feet.
Don’t forget about the CNN “moderators”. Their function will be to protect Biden from every angle of attack and make Trump look as bad as possible. And they have had plenty of time to rehearse ways of doing it.
I think a lot of people are in denial about the extent of the role the “moderators” are going to play in terms of manipulating perceptions to Biden’s advantage. I doubt that Trump is even ready for the degree to which they will go to silence him. This is not going to be your grandfather’s style of debate.
This is existential stuff to the Left. This event will be staged and managed like no other one before it. Nothing left to chance.
