This story is not at all a surprise.

This is why white racism is so terrifying to me. Yes, there's racism in every skin-color group of people, but when was the last time you heard someone of color decide to assassinate a Presidential candidate because he was a white man?
If Obama does not get elected because someone killed him, I will most likely change as a person. And it won't be for the better. Because it has already happened one time too many. If it happens again, I'll need some serious conditioning not believing in complicit guilt by apathy and indifference.
DO NOT LET IT HAPPEN, people. Being black SHOULD NOT be a DEATH SENTENCE.
