What candidates promise often doesn't come to pass, for a variety of reasons. Trump was elected with a higher percentage of evangelical Christians than any other president, and he was endorsed by the most influential evangelical leaders. Why? Trump is morally and ethically repugnant, and has never had any church affiliation. By any fair and impartial judgement, Hillary Clinton was by far the better, more experienced and smarter candidate, and despite the twenty-year effort of the far right to smear her, ethically she is pretty clean. She will not be locked up, as Trump's awful crowds screamed for.    https://www.nytimes.com/video/us/politics/100000004533191/unfiltered-voices-from-donald-trumps-crowds.html
Watch that video, listen to that angry filth.  Those are the REAL: Americans who voted for Trump.

Bernie Sanders lost because he didn't have the votes, period. His supporters stayed home on election day and total voter turnout was low. That's how we got Trump.
