Those were figures NBC threw out the minute the polls closed. Here are the revised ones... NBC exit poll: http://www.nbcnews.com/politics/2016-election/primaries/SC Clinton took whites: 54 to 46 Clinton took blacks: 86 to 14 Sanders took white men: 56 to 44 Clinton took white women: 60 to 40 Your other question... White college graduates: Clinton 52 to 48 White non-college graduates: Clinton 57 to 43 Non-White college graduates: Clinton 89 to 11 Non-White non-college graduates: Clinton 83 to 16 So much for Bernie's college kid revolution.
Might be for Latino, Asian, and Muslim college kids too. We can't tell from the SC numbers because there are none in SC.
Maybe, I do wonder about the overall Muslim vote, I would not be surprised if he beats Hilary there, would not be bad for a secular Jew to win that segment of the vote.
