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.
Fairfax has taken a sharp turn left the other D.C burbs may follow suit. As far as VA going Dem. In a landslide election, (PV by 6 or so) probably. Other than that the Dems do have a chance of getting VA with Warner. Warner has a lot of appeal in the rural portions of the state thare are moving right. Warner running makes the D.C burbs fly even further to the left & offsets & possibly retratcts slightly the GOP growth in SouthwesternPA & the Valley (obviously going against Allen dismisses this from ahappening)
Center to right with the ever increasing number of military and government contractors balancing out the DC sprawl.
