Fun Fact: Clinton Beating Sanders 16-4 in States that Have Conducted Primaries Rather than a Caucus

[Zynx]

15. The exit polls showed it. As a percentage of the Dem electorate, they're often a majority.

In states where the Dems get 40-45% of the vote and African Americans are 30% of the overall electorate with 90% voting for the Dems, it stands to reason that the vote is predominantly black.

You are being pretty rude for someone who clearly isn't actually thinking about this with any level of sophistication and for someone who is making arguments that also invalidate Sanders's wins. Low turnout? How about those caucus states? States we won't win? We'll win Virginia and Florida long before we win Idaho or Oklahoma.

Since I assume you're too strident to actually look this up for fear that you're wrong, I'll do it for you:

Georgia: 51% black http://www.cnn.com/election/primaries/polls/ga/Dem
South Carolina: 61% black: http://www.cnn.com/election/primaries/polls/sc/Dem
Alabama: 54% black: http://www.cnn.com/election/primaries/polls/al/Dem

They don't have them for Mississippi and Louisiana, but there's no doubt that holds there.

Bernie got basically none of the southern African American vote. Deal with it. It's not my problem you're being strident.
