A new SurveyUSA poll of the Virginia gubernatorial race finds Republican Bob McDonnell leading by 15 points over his Democratic opponent, Creigh Deeds. This represents the largest margin either candidate has enjoyed in any poll since the June 9 primary.

The GOP candidates for lietenant governor (which is voted on separately from the governor) and attorney general also lead by double digits.

Deeds led in the first poll taken following his darkhorse primary victory, but McDonnell has led in every other head-to-head survey taken over the last seven months. McDonnell defeated Deeds in the 2005 attorney general race by just more than 300 votes.

McDonnell 55
Deeds 40
Und 5

McDonnell now leads by 6.3 points in the RCP Average for Virginia
