I recall Obama himself, delusional idiot that he is, claiming at some point that "if blacks just voted their numbers, we'd turn states like Mississippi blue" or something like that.
Which I think is true. If blacks voted in the same numbers as whites, percentage wise, I'm pretty sure Obama would have carried Mississippi. I could be wrong, though.
I somewhat agree but still, wouldn't Obama have to get a larger share of the white vote, and seeing as how it's Mississippi, I don't see that happening for him or for any Democrat for that matter. Mississippi's African American population would have to increase and nearly mimic the total number of whites. The state as a whole isn't very diverse; it's mostly just white and black (a very insignificant amount of Hispanics, Asians, Natives and other ethnic minorities).
However, if African American turnout was higher than the white turnout, then the state could possibly turn blue, but like I said, I just don't see that happening anytime soon.
