Who can be the next president of USA?

I am thinking the next president could just be Hilary Clinton. So far I think all the contestants in the US presidential race are very capable. Whoever wins on the long run will surely, in my opinion, not disappoint.

If Hillary beats Bern for being the democrat rep, she will be the one to be matched against Donald Trump. We cannot underestimate Trump because he is a Billionaire and he can use his money for marketing of his campaign. I think the election will be very unpredictable.
