Mississippi exit polls:
White voters: 72% for Clinton, 27% for Obama
Black voters: 9% for Clinton, 91% for Obama
This, sadly, is not inconsistent with all other states (I’m lookin’ at you, Ohio), but it is more pronounced than any I’ve noticed.
(All my photos of the Jackson rally here.)
ADDENDUM:
Asked in exit polls whether Clinton is “honest and trustworthy,” 52% of the voters said yes, 48% said no. Same question for Obama, 70% yes, 30% no. I wonder how many people said that Obama is honest and trustworthy, that Clinton isn’t, and voted for her anyway.
