Any questions you have will be really useful for me to create an "about" page that explains what it's doing. The main purpose of this site is to give people an easy way of seeing who is actually expected to win the election. The site uses betting markets as it's source because that's a better indication of who is actually winning. Even though some polls show Trump has tied or even ahead of Clinton, Clinton is still a favorite over Trump.

I just picked it up. Started with Trump because I figured people would be googling some form of "Is Donald Trump really going to become president?"
