Reagan had been on the radio, was a movie star, and on T.V.; of course he was good at talking/projecting an image etc.!
Nixon? He was good and yet, he had bad times as well, on screen.
Trump was just fine, tonight, but he has to figure out a way to "hide" his breathing pattern.
I don’t mind the breathing. I don’t want my heroes all sanitized, practiced, airbrushed, and plastic like some of the characters we’ve seen tonight.
