Story highlights Republicans have not won a statewide race in Virginia since 2009

The GOP hopeful narrowly lost a US Senate race to incumbent Mark Warner in 2014

(CNN) A poll of the race for governor of Virginia published Monday shows that Democratic Lt. Governor Ralph Northam has opened up a 17-point lead with likely voters over Republican Ed Gillespie, a former adviser to President George W. Bush.

The poll conducted by Quinnipiac University comes a little more than a week before voters go to the polls, showing Northam leading Gillespie, 53% to 36%. Libertarian Cliff Hyra garnered 3% support.

Despite the encouraging numbers for Democrats, a source familiar with the Northam campaign's thinking said that while they believe the lieutenant governor is leading the race, the margins actually are much closer. Prior surveys are consistent with that theory. A tracking poll from the Wason Center at Christopher Newport University shows the Democrat with a seven-point lead. The Wason Center will issue the results of their final tracking poll the Monday before the November 7 election.
