I used to travel to VA in the last 90s, early 2000s on business to the Fairfax area. It didn’t seem to be Blue at the time.
...hmmmmm; for many years, those of us living in “real” Virginia refered to that part of the Commonwealth as “The Peoples’ Democratic Republic of Northern Virginia”...yeah; with the untold thousands of federal employees, contractors, beltway bandits, and all the others feasting off the public fisc, that area has been blue for quite some time...
It has been trending Blue since Obama.
