Mostly I think Trump won because Bernie Sander's people in the rust belt didn't vote, or actually voted for Trump, based on Hillary stealing the primaries from him. That's my idea about this, perhaps I'm wrong but it is at least a part of the reason for Trump's victory.
Afraid, I think everyone should be afraid this guy doesn't seem to have a plan, he looks like the Brexit negotiations, he says one thing one day and then he back tracks the next. Not that I think Hillary was any better.
