There is no recount in Virginia any more. They have switched to paperless machines for the most part. Therefore the recount is just verifying the printout from the machine.
There aren't hanging chads, or anything like that. Allen barely lost. There aren't 7,000 votes out there for him.
You're quite naive if you think this system can't be tricked, and there's already 3700 votes that flipped because of a misassignment.
I voted by paper ballot in Leesburg in Loudoun County. Folks were offered a choice of either paper or computer (no hanging chads...we took pens and bubbled in the ballots in privacy screens).
So who knows. :P
