Where is everybody coming up with double? If Romney got 6% of black vote in 2012 and Trump is around 18-19%, isn’t that triple?
BHO got 97% of the 100% in 2012. Let’s take 10,000 votes. SO baseline he’d get 9,700 . Now, with 16% down, that 10,000 is down to 8,400. And of that, HRC loses another 900 (the extra 9% to DT) . So at min we’ve gone from 9,700 to 7,500 votes for HRC.
