Are people really going to vote for him?
Better to think of it another way: People are going to vote for him based on what he is perceived not to be - an establishment politician.
Are people going to vote against an establishment politician like Hillary? of course. When people are looking for the 'magic' of Trump they are looking at the wrong thing, it is about what he is not, rather than what he is. It's not very difficult to work out why people would vote for anything other than 'business as usual'. Trump happens to be in the right place at the right time.
Hillary probably only has a chance to win against Trump, and Trump probably only has a chance against Hillary. Both sides are going to choose the least popular candidate they possibly could. It's probably going to come down to who is the least unpopular, and they are both very unpopular in general.
