Fairfax County, Virginia's largest jurisdiction, re-opened for the business of voting on Tuesday, inviting voters to come from 4-8 p.m. to its central voting location -- but not the seven satellite offices -- to cast in-person, absentee ballots.

Fairfax and dozens of other local governments in Virginia suspended absentee voting on Monday as Hurricane Sandy approached the east coast. Some of those cities and counties stayed closed Tuesday as well.

Fairfax was key to President Obama's victory in Virginia in 2008; the county delivered the Democrat a 110,000-vote winning margin against Sen. John McCain (R-Ariz.) -- nearly half of his 235,000-vote winning margin among 3.7 million votes cast. Absentee voting was also crucial to the president; he won absentee votes overall in Virginia by more than 120,000 votes.

Gov. Robert F. McDonnell (R) has urged local registrars to keep absentee voting open late in the coming days to make up for curtailed operations Monday and Tuesday that resulted from the storm.
