They have Latinos at only 9% of the electorate, too. I know, subsample MoE, but that's your problem right there. Trump is only winning white voters by 12 points in this poll, and if that happens, Clinton wins handily.
Why are you analysing this post selectively? 12 point lead amongst whites is ok but 15 point deficit with Latinos is not ok.
Yes, because 12 points is reasonable - at most he will have a 15-18 point lead with whites, esp with college educated whites swinging to Clinton. However, no one in their right mind thinks that Hillary will underperform Obama with Latino's...and in fact, Latino Decisions puts her margins at "historic" levels, probably +60.
