Having watched the entire speech, although not a polished spokesperson, Trump gets his message out and most importantly, in a positive way. He speaks in plain terms and without a lot of politically correct gibberish. Certainly he has an ego larger than life but what he is doing is creating a positive image in the audience, by doing so he enhances his popularity with the people. Telling them what they want to hear is exactly why he is leading so widely in this race. The nation is tired of the odumbo administrations failings and drastically seeks a shinning beacon of hope.
Please notice that Trump always has a humorous undercurrent in his speeches even if it is only sarcastic put downs of his opponents. He strives to be entertaining. It is not a dry delivery.
Where is Trump’s teleprompter? I remember a certain potus using totus at a grade school!
