It means the next president will be Republican again

If Hillary gets more support, I can say Democratic will win the president election for sure.
But now, Obama gets more support which makes whole different story.
Since in US, majority of the people still can not really accept a black guy to be president.
So, during the final election, if it's Obama vs. one of the Republican, he will lose for sure.
Since people who lean to democratic might turn to support Republican just because of Obama is black.
