in 2005, won the four major fast-growing counties in Northern Virginia outside Washington, D.C.; Fairfax, Loudoun, Prince William and Arlington. President Barack Obama carried Virginia by a 6.3% margin over Republican Senator John McCain. When results began coming in, Allen quickly built a sizeable lead, which began to narrow as the night went on. With 90% of precincts reporting, Allen held a lead of about 30,000 votes , or about 1.5%. However, as votes began to come in from population-heavy Richmond, Webb narrowed the gap, and pulled ahead within the last 1 or 2% of precincts to report. Preliminary results showed Webb holding a lead of 8,942 votes, and many news organizations hesitated to call the election for either candidate until the next day. At 8:41 PM EST on November 8, AP declared Webb the winner. In all Virginia elections, if the margin of defeat is less than half of a percentage point, the Commonwealth of Virginia allows the apparent losing candidate to request a recount, paid for by the local jurisdictions. If the margin of defeat is between one and one-half of a percentage point, the losing candidate is still entitled to request a recount, but must cover its expense. Because the difference was less than 0.5%, George Allen could have requested a recount paid for by the government, but declined to make such a request. That was likely because: Even in large jurisdictions, recounts — such as those in Florida in 2000 and Washington's 2004 gubernatorial election — rarely result in a swing of more than 1,000 votes, and Allen was trailing by almost 10,000 in the initial count. In particular, almost all votes in this Virginia election were cast using electronic voting machines, whose results are unlikely to change in a recount. There was wide speculation that calling for a recount (and still losing) would give Allen a "sore loser" label, which would hurt his future election campaigns, including what some speculated might still involve a 2008 presidential run. However, after losing the senatorial election, on December 10, 2006, Allen announced that he would not be running for president in 2008. Washington Incumbent Democrat Maria Cantwell won re-election to a second term. The filing deadline was July 28, 2006, with the primary held September 19, 2006. Cantwell consistently led in polling throughout the race, although political analysts saw her as vulnerable this election cycle due to her
