You need to look at the precincts that submitted their tallies late.
I suspect you’d find that they were in Richmond, Hampton, Alexandria/Arlington and certain areas of Fairfax and Prince William Counties.
Where the people counting the ballots waited until they knew how many votes needed to be manufactured without it seeming too obvious they were doing so.
Seems logical to me. Sounds like the 2004 vote in WA State, when Christine Fraudoire (D) “defeated” Dino Rossi (R). Every time Rossi had a lead, election officials in King County (ultra liberal Seattle) would suddenly “discover” a box of uncounted ballots, that coincidentally, were just enough to put the DemoNIcrat, ahead. I really fear that control of elections have been lost, in our country :(
