Yeah, that has me concerned, even though NC went Romney in 2012. Remember that guy from NC in 2012 boasting on his facebook about voting multiple times?
I lived in NC from 1997-2001. I was surprised at the large Mexican population in
Winston-Salem, where I lived
My guess is the big surprise of the night is that Trump will win Pennsylvania. The demographics of the state really work to his advantage. It is the second oldest state (not as many younger voters) and has a very large rural white population that has been hurt by trade agreements.
I grew up in PA and have family in PA, so I know the state well. Hillary is not going to get the African-American support that Obama received. Just a hunch on my part, but I think Trump carries PA.
