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.
If we look at Trump v Clinton directly Trump has 62% of the white vote. Romney got 60%. Clinton gets 76% of the non white vote. Obama also got 76%. If turnout is the same as 2012 then it's 51-49 Hillary. If we look at white college grads Clinton is at 52 when Obama got 44. On non grads it's Trump on 69 while Romney got 62. Numbers like that lock Clinton into the Obama 08/12 states (FL VA CO etc) but perhaps give Trump a shot at OH PA. The internals don't really point to a different picture than what we've seen all summer.
