"On March 26, Democracy for America, one of the largest political action committees in the country, launched its Purple to Blue Project, “a national, multi-year effort to win state House and Senate chambers across the country by making so-called ‘purple’ state legislative seats decisively Democratic,” according to the announcement.
Battlefield No. 1: Northern Virginia.
Within the Purple to Blue effort, the PAC boasted it would spend more than $750,000 in five targeted Virginia state house contests, three of which covered parts of Loudoun – the 34th, 86th and 87th District races....
On Nov. 5, Comstock, Rust and Ramadan carried their districts – albeit in barnburner fashion – and sent a message to state and national political operatives that Northern Virginia isn’t yet the steady Democratic stronghold it’s often made out to be."

The only Northern Virginia delegate who lost re-election was L. Mark Dudenheffer (R-2) of Stafford and Prince William. Delegate-elect Michael Futrell (D) defeated him 51-49 (mainly by utterly crushing Dudenheffer in the Prince William precincts). Interestingly, neither party had thought the second district was all that competitive of a race going into election day and it wasn't a targeted seat.
