You do realize that many of his supporters are blue-collar and middle-class heartland types, people just like me and presumably you.
Your post is the very definition of elitism.
You simply can't slander a bunch of people who do this:
"But at a rally Thursday in an arena in Baton Rouge, La., Mr. Trump's supporters treated his profane remark about Mr. Cruz like the hit song of a touring rock band, pleading with him to let it rip again.
They're all saying, “Do it! Do it!” he told a clamorous crowd of nearly 10,000, acknowledging their chants."
They are like a bunch of bloodthirsty savages.
You know, I’m “bluecollar” and middle class, and surrounded usually by same. I, nor those that I hang with, consider speaking crudely in public forums, especially in mixed company. I don’t see what being blue collar has to do with being boorish, some seem to wear it as a badge of honor.
