Former congressman Tom Perriello has landed a new job.

Perriello, who lost his House reelection bid in 2010, has been named president and CEO of the Center for American Progress Action Fund, the advocacy arm of the liberal think tank.

In 2008, the Democrat won his sprawling, largely rural district — from Charlottesville to the North Carolina border -- by 727 votes. But he lost the seat two years later, even with a last-minute campaign stop by President Obama.

Perriello, who unapologetically backed progressive policies, has been a favorite of grass-roots activists who have often mentioned him as a future governor, U.S. senator or state party chairman.

He, in part, replaces Jennifer Palmieri, who joined the White House as deputy communications director. (Tara McGuinness also replaces Palmieri as senior vice president for CAP Action and senior vice president for communications at the center).
