The interesting phenomenon is those traditional pockets of Democratic strength in mining counties that were unionized at the cost of many lives that broke with tradition and went Republican this election.
The problem is that the returns in those areas are complicated by the general pattern of low swings to Obama (or even swings against) in other traditional industrial areas (just have another look at the PA and OH swing maps. Yeah, the former is distorted by media market stuff, but the patterns are clear all the same) and, of course, by the awful turnouts there. There are several counties in West Virginia that saw a sizeable swing to McCain but where it seems less people voted for McCain than for Bush four years ago.
