Unlikely, IMO; whites are actually going to be better for Obama in North Carolina than in Pennsylvania, despite what conventional wisdom about the South would tell you. Mainly because there's no equivalent to the Pittsburgh area in North Carolina.
Mmm... yes and no. There are certainly a lot of industrial townships but, of course, many of these tend to be historically Republican. And historically based around textiles rather than being founded on iron-steel-coal. And with very low rates of unionisation (legacy of the failed strike of 1934).
