Though I wouldn't be surprised if Mitt Romney gets fewer votes out of SW VA than McCain did. Really Romney should be doing better than McCain in NoVA, so the fact that Obama hasn't lost that much of his 2008 margin in the state means he's making up ground somewhere else.
Obviously we don't really know regional details like this at this point, but it wouldn't surprise me if Obama is outperforming 2008 in Hampton Roads. Romney is a much worse candidate for the military community there than McCain, and Obama is probably a better candidate for them now than in 2008. The first of these is kind of true for rural VA, but the second isn't.
