Virginia is trending ever so slowly but inexorably from the right to the center as the Washington metro area suburbs expand, and the suburbs nearer to DC mature and become more Democratic over time the way Fairfax County has done -this is assuming we're talking in terms of decades, and not in years.
I would agree for the most part. I think that the Northern Virginia suburbs will move slightly to the left on the basis of social issues. However, the move to the left in Northern Virginia is offset in some respects by the move to the right in the Valley and Southwestern parts of the state. The belief that Virginia is somehow going to vote Democratic in Presidential elections in the next ten years is somewhat unfounded I think.
