Also the respondents were 55% female and 45% male. Is the gender gap expected to be that big?
That's pretty typical in the South as black men have terrible turnout, but black women actually have great turnout compared to white women (whereas there's not much difference in turnout between white men and white women, or among other ethnic groups more generally, so the largest gender gaps tend to be in areas with large black populations, i.e., the South). It's of course even more pronounced in Democratic primaries, where the electorate in some Southern states can be as much as 65% female.
