A left-leaning group is set to air its third TV advertisement against the Republican candidate in Virginia's gubernatorial race. Common Sense Virginia is launching today a 30-second ad titled, "Jobs Governor," which combats former state attorney general Bob McDonnell's campaign mantra -- that he'll create jobs.

"Bob McDonnell has a long record of opposing help for Virginia's unemployed," said Common Sense Virginia press secretary Yoni Cohen. "McDonnell is out of touch and voted again and again to ignore the challenges Virginians face in tough times. When McDonnell claims he'll be a 'Jobs Governor,' he's gotta be kidding."

It appears to be an extensive ad buy, as the spot will air in Northern Virginia, Richmond, Norfolk and Roanoke -- the four largest media markets in the state.
