Does someone who knows MS/AL demographics want to explain these county maps?
To simplify...
With AL - Gingrich won in the black belt, Santorum won in northern Alabama (which is full of all of those used-to-be Democrats who switched based on social issues) and Romney probably won in the suburbs and urban areas, though I'd have to look precinct by precinct there. I said the polls were most likely to be way off in Alabama b/c most of the Santorum north Alabama folks still identify as Democrats and might get knocked out of the likely voter screen (same thing happened in 2008, btw)
With MS - Somewhat the same, though Mitt Romney had a better showing in the black belt here, which may well be due to Barbour's machine.
