I will say, given the demographic breakdown among whites (grads vs no college) the Latino Decisions poll and what we expect from African-Americans, Hillary should be comfortably ahead in the electoral college. I just don't know how this poll was weighted.
The fact there are no numbers fro young people says they undersampled young people.
I did some back of the envelope math and the white vote in this poll was 76% so maybe it is souped up a little (2012 white vote was 72%). Additionally Trump leads by 39 with non-college educated whites but Clinton leads by 5 with college educated whites. They are equivalent portions of the white vote (meaning they are about the same amount of the overall electorate) so we should be seeing a Trump +17 with whites instead of Trump +22.
There's how you get his lead. It was souped up a little with far more whites without a college degree and a lower % of POC
