” Hillary, I have a yes or no question. And this is before God. Have you ever lied to the American people?”
These would be certain to set off bobblehead and then cause her legs to fail.
Then, I would turn to the camera and say, “I don't think she's been entirely open with her health issues.”
The debate would be over as they carted Hillary to the ER.
I don’t know if there are formal rules about standing/sitting but I remember a Clinton/Bush “town hall” debate where the candidates each had a stool and no podium (recalling the ponytailed guy who asked Bill to think of us all as his children...).
It’s all about “looking presidential” and debate analysts made a deal about Nixon looking “shifty” in his debate with JFK because he had discomfort in his lower legs that caused him to keep shifting his weight from one leg to the other while JFK stood erect.
In NO WAY should Trump wander over to Hillary’s side of the stage like Lazio did. The magnitude of his presence will be enough where such theatrics aren’t needed. In fact, the more serious and CEO-like that Trump behaves, the better it will look for him.
Nonetheless, the hot camera lights in a studio will be enough to make any debate an endurance test for Hillary. She’ll be very uncomfortable and I wouldn’t be surprised at all if she tries to duck the debates as much as she can.
I would also recommend to Trump to wear a vest under his suit coat. It would have a look of being very serious and presidential. I remember Ford did this against Carter in '76, and it made an impression. Of course, Ford screwed it up by saying Poland wasn't under Soviet domination later on in the debate.
She will need railings and several steps to sit down on her stool.
