A new Daily Kos/Research 2000 poll of the Virginia gubernatorial race shows that the race is up in the air in this swing state, with Republican former state Attorney General Bob McDonnell having a one-point edge over Democratic state Sen. Creigh Deeds.

The numbers: McDonnell 45%, Deeds 44%, within the ±4% margin of error. In a poll from two weeks ago, before Deeds went on to win his three-way Democratic primary, McDonnell enjoyed a 46%-34% advantage.

McDonnell previously defeated Deeds in the 2005 race for Attorney General, by only a few hundred votes, back when the state was much more friendly to Republicans. Since then, Virginia has voted in two Democratic Senators and gave its electoral votes to Barack Obama last year. The race this year could end up telling us all a lot about whether the state has shifted definitively into the Dem column.
