A new restricted trailer for director Jay Roach’s The Campaign has debuted.  The political comedy features Will Ferrell as a slick incumbent who is at odds with the oddball dark horse (Zach Galifianakis) in a Congressional election race.  While you can learn a lot about the film from our recent set visit and interviews with Ferrell, Galifianakis and Roach, the new restricted trailer goes back to the old Ferrell comedy stand-by: the family dinner table.  It’s not quite as funny as the kids from Talladega Nights: The Ballad of Ricky Bobby, but there are some good one-liners.  Hit the jump to check out the new restricted trailer before The Campaign comes to your town on August 10^th.
