Are Pollsters Expecting Minorities to Vote in 2012 Numbers?

I see the polls between Hillary and Trump are sorta’ kinda’ tight.

And I’m not about to say all the polls are wrong. I jumped on that bandwagon in 2012. But I am interested if anyone knows if pollsters are basing their minority turnout models on 2008 and 2012?

If so, is there any reason to suspect that the minority community will turn out in numbers for Hillary like it did for Obama?

Just wondering.
