No he can't. No one can. The revolution against DC speak is what this is all about. It is why we recognize Putin's competence in running Russia. He says things that mean something and make sense - even if they are frequently not to our benefit. Listen to McConnell or Hillary or any of the others - you have no idea what they will do - except make sure that they pay off all the people who have shown up to be paid off.
I would concur with Defiant. If he needs or wants to, he does have the ability to speak “fancy DC Speak.” But, he’s obviously well grounded enough to speak and converse with us regular folks. To phrase it in an old fashioned way: He shoots from the hip. Unlike, McTurtle and Billary, he’s genuine and genuinely cares. Unlike what we hear from the MSM, we learn of Trump’s genuineness and integrity from regular people who have actually met him, even in passing, as well as people who have done business or worked with him—without fancy fanfare or staged events. Having integrity is something that is not in the Liberal, nor DC-Elitist, chromosome.
Maybe we are talking two different things, but I am referring to a specific speech that was organized and had all the nice big words that ivy leaguers understand and that set forth what he wants to do in a coherent fashion. It is different from most DC Republicans because it is America first, but it shows he can give a speech like that instead of the kind of speech he gives at rallies. They are two different things for two different audiences, but the message is the same, even if the delivery is different. Many critics want to focus only on the rallies and then critique that it is rambling, instead of look at the substance.
