A former presidential campaign staffer for Newt Gingrich (R) is launching a push to convince his old boss to run for the Senate in Virginia.

Gingrich's 2012 New Hampshire state director and national digital fundraising director, Andrew Hemingway, is spearheading the push.

"We want a credible challenger to Mark Warner, and no one could do what Newt could do to fight -— and win," he says in a statement announcing the group. "U.S. Senator Newt Gingrich would be an immediate game changer, giving conservatives another voice that would take the fight to the Obama administration."

The prospects of persuading the former Speaker (R-Ga.) to run seem highly uncertain. Gingrich, who has lived in Virginia's suburbs for years, recently took the job as a host of CNN's relaunched "Crossfire." Warner's approval ratings have been rock-solid in the swing state.

But Gingrich, who has high name recognition and a flair for drawing media attention, could make the race a lot more interesting if he decides to run.
