Prince William County is just north of my county (Stafford). It has been liberal for quite awhile. My friend and neighbor, a very conservative man, was voted into the House of Delegates six years ago. The Republican legislature actually redistricted him and added a part of P.W. County in his area and he lost the next election. He did gain it back two years ago but became so sick of "business as usual" that he refused to run this time and a liberal from P.W. won over the Republican to take my friend's seat.
Anyway, Prince William County has become a bastion of liberalism.
It has turned exactly to that.
