Should be noted that other polls have Trump doing not quite *that* badly among blacks. E.g., the recent Pew poll has him at 7% in the 2-way matchup:
Trump is doing mildly better with Latino's than I thought he would be at polling at 24% support with them. I thought he would be polling at 15% with them.
Trump is getting killed with Women by 24% points though and with college grads(but not post grad) 54-38%.
Trump is doing closer to the lower medium end of the Black Vote that Republicans have done in the past:
McCain 5% of the Black Vote in 2008
Romney 6% in 2012
Reagan 8% in 1984
Bush W. 8% in 2000
The High End:
Reagan 14% in 1980
Bush H.W. 12-13% in 1988
Dole in 1996 with 13%(because of Kemp being VP candidate.)
Bush W. 12% in 2004
