Senator-Elect Jim Webb currently leads
1. James City County Absentee (C003)
2. One of two precincts in James City County called "Roberts B (0502)"
3. Raynor in Isle of Wight County.
4. Fairfax City Central Absentee Precinct (C011)
In James City County, there are no voters left to count in their county. Long story short, all of the voters in James City County live in Virginia's first district. The uncounted "precincts" of that county that are in VA-03 are part of the James River. There are no more votes for anybody outstanding here.
The last two districts will - at best for Allen- add only a few dozen votes for him. Based on '04 turnout numbers, Raynor only had 170 total voters (+17 for the GOP) and Fairfax City absentees went heavily for the Dems. Most likely, Webb's lead will grow slightly.
Expect Sen.-Elect Webb's current lead to remain largely unchanged - he will be certified the winner of this Senate seat. After that, Allen will be allowed to call for a recount.
