The reality is that a lot of his supporters (again, not all) have come to identify with him. They love it when he engages in "plain speaking" (i.e., insults),
Trump's "plain speaking" goes well beyond "insults". Trump does the best damn job explaining economics, the relationships between corporate inversion, NAFTA, TPP, and job creation.
Trump's "plain speaking" explains not only that NAFTA is obsolete, but why and how we can and should change it.
Trump's "plain speaking" resonates because a nation without secure borders will not be a nation for long.
Trump's "plain speaking" explains why we need to replace Obamacare, CommonCore and the best replacements for both.
Trump's "plain speaking" has put political correctness on the chopping block--and those who hear him understand why.
Trump's "plain speaking" does not differentiate between young and old, rich and poor, white, black, red or green. Trump's "plain speaking" invites all to join in making America Great Again and be its beneficiary.
I post links to live streams of Donald Trump's almost daily rallies. I invite you to click on one of those links and listen to him. Just sit back and listen to him....you don't even have to tell anyone you're doing it. You'll hear political red meat, for sure. But you'll also hear clear answers to what is destroying this nation from the inside out.
Listening to him will also help you understand why Trump's "plain speaking" is just one of the gifts his competition wishes they were blessed with.
