I will put it this way, Trump is not slick, he is not a lawyer, he is used to, in his own business, of giving answers and is not afraid to say that he doesn’t know yet or have an opinion on something.
Cruz, like Hillary, Obama, Rubio, BJ Clinton, Chris Christie, etc are highly trained lawyers, they are trained to not answer questions. I have seen it where Trump says more in 20 seconds then the above listed group in 2 hours.
Yeah Trump is the most WYSIWYG candidate in our lifetime. The lawyers you listed are mostly snakes and sneaks.
