The actor-comedians spar as rival politicos in The Campaign, an election satire directed by Jay Roach, which just released its official trailer following an amusing double feature of mock political ads.

Ferrell recycles his SNL-honed George W. Bush impression on incumbent U.S. congressman Cam Brady, who has a twist of John Edwards-esque sleaze. "My hair could lift a car off a baby if it had to," he brags while gazing at his reflection in the mirror.

His foil in the race is Marty Huggins, a twee family man with a Ron Swanson mustache, portrayed by Zalianakis, who shoots an arrow in Brady's direction in one scene.

The film premieres Aug. 10, and co-stars Jason Sudeikis, John Lithgow and Dan Aykroyd.
