Obama won Virginia in large part because of the ever-increasing number of democratic voters in Northern Virginia. Mark Warner, Jim Webb, and Tim Kaine all can credit NoVa with providing the margins of victory in their senate and guber races (with massive assists from Macacca and the world's worst governor, Jim Gilmore).
In their pursuit of a smaller government, over the last 30 years the Reaganites have created this monstrous democratic voting bloc. As the have budgets shown, republicans never shrank government in any meaningful way, they just outsourced it to a gigantic network of contractors, call it the information-industrial complex or something. Where there once were farms and sleepy towns now are Grant-Thorton, Northrup-Grumman, SAIC, AMS, Raytheon, and tons more that you've never heard of. These contractors hire educated people, and overall they pay them decently.
There are a lot of downsides to this informational-industrial complex (incredible amounts of waste, weak oversight, annoying names), but as far as politics go, nothing spells death to the republicans like "educated middle class."
Thanks again, jackasses.
