I don’t buy this view of what the Virginia results “mean” for the nation as spun out by a Dem strategiest, but this part seems mostly correct:

In reality, exurban voters are tax-sensitive and concerned about government waste, but not ideologically anti-government. They tend to be religious and family-oriented, but socially moderate in comparison to rural residents. They are not anti-business, but they do hold populist attitudes toward corporate abuse and people who game the system. And they worry as much or more about public education as they do about moral values.

Allow for regional differences, and that quickie description of the broad middle is on target. What it means for politics and policy, however, I have yet to figure out.
