As I just commented in a short discussion with a co-worker with similar political leanings, firstly, I expect that Hillary may win because there really are that many idiots out there that would vote for her. People that just can't see the real Hillary and can't understand what they would be voting for if they support Hillary.

Thirdly, well, related to the first two items here, Hillary's administration and the scandals and failures that would likely come from same would likely teach many individuals to be careful what they ask for as they just might get it.
