I don't think it's racist at all, I think it has to do specifically with a certain feeling a lot of people have had that Obama may be in some real danger. Huckabee made the error of voicing out loud a thought that lurks nervously in the back of a great many people's minds...not necessarily because Obama is Black...but merely because it looks as though he could win the election now. (I know this because I have heard a number of people say privately that they were worried about it. I have not heard anyone worrying about Hillary or McCain getting shot. Huckabee slipped, and he publicly voiced that thought out loud.)

Bobby Kennedy did not get shot in '68 because he was White. He got shot because he was on his way to winning the Democratic nomination and the presidency...and there were some very powerful people who didn't want him there.

Get it?
