Trump is not getting 19% of blacks here. NV is safe for Hillary.
Nevada is only 9.3% African-American. VAP is even less than that. Assuming Trump receives 0% of the black vote, Trump would only lose 1.7 points - and that assumes turnout will be 9.3% African-American. It will be less than that, and some African-Americans will vote Trump.
So MAYBE Trump's numbers are off by a point because of the allegedly high black percentage. Hardly enough to make NV safe for Hillary.
Well, I could also point out that Hillary is likely to get much more than 58% of the Latino vote, but I've talked about NV enough. I called it for Hillary from the beginning, and I'm standing by that call.
