Briefly: if you are a black Mississippian, you voted Obama, if white, Hillary. Obama won 91% of blacks, Hillary 74% of whites. That's unsettling.
But here's an interesting stat. Republicans made up 11% of the vote, and Hillary won 85% of them. Limbaugh? Maybe so: Independents split roughly evenly.
Another interesting stat. CNN asked voters of both candidates whether they had a positive or negative opinion of John McCain. Counter-intuitively, Obama voters were more unfavorable (71%) than Clinton voters (29%)--but maybe that's just because Obama voters are Southern blacks who strongly mistrust the GOP.
Further fraying is evidenced in this finding. 74% of Clinton voters find Obama untrustworthy, and 92% of Clinton voters find Obama untrustworthy. The kitchen sink strategy has born toxic results!
Weirdly, only 58% of Clinton voters would be "satisfied" if she won the nomination. (Danger!) 84% of Obama's voters would be satisfied if he won.
No results in, everyone's calling it for Obama.
Full exits here and here.
