As much as I dislike Trump, he's no Hitler.  Has he borrowed a few pages from his playbook, yes!  Does he use fear tactics, absolutely.  Is he relying on the under educated, of course.  He admits it.  This combination of shoddy, unethical tactics have garnered him millions of supporters.  How he won over evangelicals is easily explained.  In my opinion, it's that common thread, that familiar element of borderline hysteria that we recognize with religious zealots - fear and fantasm.  

Get that adrenaline going, like a preacher at the pulpit, and his followers are hooked regardless of what nonsense he spouts.  And like so many preachers at the pulpit, Trump is purely self serving.  He never has and never will do anything to promote the common good.  He doesn't know how nor does he care to learn.   Vague, empty promises to promote his own agenda and that of his children - that's it!  It shouldn't take one of his peers, Mark Cuban, to point this out.
