http://www.nationaljournal.com/next-america/newsdesk/trump-lead-alienates-white-collar-voters I like some of Trump's antics. He can be funny but I can't say I am surprised at this. If you check out some of the stats, he polls quite poorly with republicans with a college degree. When it comes to high school grad or below, he polls 2-1 to the next candidate.
Trump has the appearance of succeeding because he as already consolidated his base: blue collar republicans who lack post-secondary education. While he and his base keep thumping their chests over the poll numbers, the college educated republicans have yet to coalesce around one candidate, which means that Trump appears much more popular than he actually is.
Now, once the field starts to thin and Trump continues to do well, then I will say there is something there. He has to start winning the people who don't hoot and cheer over the idea of a wall on our border with Mexico.
