Even if he were to wear a device so his staff can talk to him during the debate, it probably won’t matter....
It’s normally somewhat difficult to have someone taking in your ear while you are concentrating and talking about something else...Have you ever had someone try to talk to you while you are on a phone call ?? Same thing...
Given his mental state if someone were talking in his ear to him while debating Trump, it probably would confuse him and make him worse that he already is...
I get your point but its not like they would have to talk him through every answer. All they need to do is say key words at certain points to help him out. A word here, a theme there, a fact or rebuttal point at a key time. That’s all they need to do.
Interviewer: "How do you feel now about your Nafta vote as a sentor?"

Interviewer: "Can you tell me more about why Trump can't lead this nation?"
