True. Lived in Fairfax for 25 years and watched it change from Republican to Democrat as population became more affluent. I would bet the biggest change is in the number of non-native Virginians living in the area that brought their Democratic preferences with them. Northern Virginia has lost its’ Virginia roots and it shows! That’s how Warner got elected and Moran. Still have roots in rural Virginia and that area is totally different from NOVA.
The affluence in northern VA comes from those employed directly or indirectly by the federal gubmint.
Their livelihoods depend on larger government and more money flowing to D.C. So they have little interest in a political agenda that promotes lower taxes and smaller gubmint.
