49-34 among Latinos is not likely.
They have Latinos at 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.
Take the sample out and put Latino Decisions in , then Clinton goes up 3 points and Trump down 2. When over 40% of the people who vote Democratic are minority voters, you need to get those samples right in order to get an accurate vote share for the Democratic candidate.
