"I could stand in the middle of 5th Avenue and shoot somebody and I wouldn't lose any voters."
Trump himself considers his supporters suckers. Why shouldn't others?
Exaggerating a point is how real people speak who use their own words. Not canned, focus-tested speeches like most of Washington's Stepford politicians, including Ted Cruz and Marco Rubio.
Donald Trump doesn't use speechwriters and prepared speechs. He knows his subject, he knows who he is and he knows what he wants to do.
I guess there are some people who just like having their safe zone of political kabuki and sweet nothings whispered in their ear every two years – empty affirmations. It's comfortable.
In New York street vernacular Trump was saying, i'm bad! an u be my posse an stick wid me home boyz, true id all! peace!
