I'd like to know how they actually calculated these county figures.
For example, it's accepted that whites become more conservative/Republican as their community becomes more non-white. And yet the map has Obama ostensibly doing better with whites in the Black Belt counties in Alabama.
They likely have the turnout % wrong and underestimated the % black people who voted in those areas, thus giving Obama a better showing in the Black Belt counties among whites. Blacks turned out at a higher % than whites in 2012.
