Virginia continues to be such an anomaly that it it is suspect. Look at that map, there's a gaping hole between the color from Maryland up through New England, and from North Carolina down through east Texas. That gap is Virginia.
There could be legitimate reasons for it (for example, it's a well-insured population, especially in the population centers of Northern Virginia and the VA Beach, tidewater area), but I don't know - it just has a suspicious look about it.
