What'll be the scenario for the racially divided america if Obama ends up losing the presidential race?

we all know how racially divided USA is. If Obama beats hilary and wins the democratic nomination and fails to win the presidential race will it be the death knell for the american values as far as black and white relationship is concerned? we have seen how the white america treats blacks. a simple love affair between a black basket ball player and a white girl is despised. Two days ago a court absolved white police officers of wrong doing for intentional killing of an innocent young black man who was about to get married. does these things bode well for the USA? Will God bless America for harboring such hatred against fellow beings?
