I disagree completely. The man is no idiot. Far from it. His problems, and the image he gives has nothing to do with idiocy or anything of the kind. Sure, he's coached, but he acts that way because it suits him. He's above the fray. He's incapable of understanding the natural feelings and concerns of others.
...he looks like an arrogant and dismissive douchebag.
That's because that's exactly what he is. But he's no idiot...
I disagree. He's well coached. He follows directions well. He can read with emotions and enthusiasm.
But anytime he's called upon to answer a difficult question on his feet, he stumbles, phumphers and resorts to indignation and empty bloviating. He NEVER offers a new breakthrough or innovation, a truly cutting quip, a fresh perspective or insight when he's speaking off the teleprompter.
He's a competent water carrier for the deviously intelligent people who foisted him upon us - the cabal of global marxists, media manipulators and leftwing Democratic Party operatives who selected him and groomed him. But outside of their handling, he's a community activist.
Where I live, we call that an idiot. I-D-I-O-T. Idiot.
