Just heard this on TV. Thousands are still in line after the closing of the polls at 7:00 PM. They are suspending reporting while these people vote so that results do not influence their vote.
There was a mad scramble in the middle of the day to find more voting machines for the NoVA area to accommodate the crush of voters.
6:09 PM PT: Cedwyn reports in the comments that the same is happening in Florida
6:15 PM PT: Cedwyn (again) reports that they are now reporting again. I see on Politico's site that Romney's lead is down to 9 points, down from 18 when they shut that whole thing down.
6:23 PM PT: As of 3 minutes ago, CNN reports Romney's lead is shrinking - 52% to 47%
6:37 PM PT: Romney's lead continues to shrink, down to 4.5 points
6:59 PM PT: Romney's lead down to 3.9% with 71.8% reporting. This is going to be a squeaker, and may be Romney's only swing state victory!
