I am not sure the majority of Americans who will either vote for Trump or the many democrats who will abstain and not vote think Trump is the answer to the many problems in America. It is more to do with who they don't want as their President and on that front Clinton will probably (as it stands right now) lose in November even when she will outspend Trump by tens of millions throughout the campaign.
I think both candidates are pretty loathsome. However, if you watch this video you will see why many Americans have had enough of the Clintons.
Trump is a self publicist, fantasist, bully and many other things, but the Clintons are probably corrupt to the highest degree.
