Former President Bill Clinton will hit the campaign trail for Terry McAuliffe this weekend, helping an old friend boost turnout in the much-watched Virginia governor’s race.

McAuliffe’s campaign announced Sunday that Clinton would do a three-day tour of the state beginning Oct. 27 “to discuss the importance of voting in the 2013 gubernatorial election and the clear choice facing Virginia voters” between McAuliffe and Attorney General Ken Cuccinelli II (R). The campaign did not disclose what kind of events would be on the schedule or where they would happen.

Clinton has already done multiple fundraisers for McAuliffe, and Hillary Rodham Clinton has both raised cash and offered her official public endorsement at a spirited rally Saturday afternoon at the State Theatre in Falls Church.

Both Clintons are popular in Virginia, polls suggest. Several surveys have shown Hillary Clinton leading other potential Democratic contenders for president by a wide margin. And a 2012 CBS/New York Times/Quinnipiac poll found that 67 percent of Virginia likely voters had a favorable opinion of Bill Clinton.
