Get 'em baker; and TY!
They all do, but here's the thing;
Trump is authentic, regardless. His words are spoken in just, not jest. We've been watching professional speech givers for so long that to get a genuine person up there, and occasionally going off-queue (in true Trump fashion), give a refreshing feel to his message(s).
Just to point out, you can tell when he's off teleprompter because that's when he's usually looking straighter on into the crown, with either a point, or fist shake, or "It's true…" or "100%…" or something like that. Well written speeches that he likely gets to review for edits. When he's on teleprompter, he's slightly to his right or left. All high-profile speech givers have these "tells". Watch an Obama speech. He's rarely off teleprompter. When he is, you can tell he's-he's-he's-he's-Okie doke?
