Camden County also includes several blue collar suburbs and the giant corporate park that is Cherry Hill. It is solid Dem territory (as are, sad to say, nearby Gloucester and Burlington Counties) on a national basis, but it will be interesting to see if Christie or Lonergan can make inroads into the white Democrat areas in the suburban areas of said counties.
As for Camden City, it is, without a doubt, like something out of a late night Sci-Fi post-apocolyptic movie. Makes Chester, PA look like Chappaqua.
