I live in Va. There is no official breakout of where the votes are coming from, but I would make a GUESS that early results are from lower population areas which tend to be more Republican.
On the other hand, in Northern Virginia, which has a very high population density and tends Democratic, they have electronic voting machines in most (maybe all) precincts. It seems that it ought to be quick to tabulate and verify electronically counted votes.
Thanks to all of you. Guess we will just have to keep watching.
