While Barack Obama and Mitt Romney metaphorically duke it out on the national stage, actors Will Ferrell and Zach Galifianakis are battling it out on the silver screen. And according to the Hollywood Reporter, the raunchy Hollywood flick got a bump in sales this weekend after Romney named Paul Ryan as his running mate.

Political buzz is in the air:

The Campaign, featuring Will Ferrell and Zach Galifianakis as rivals vying to represent their North Carolina district in Congress, debuted to a solid $27.4 million, slightly more than Warners was anticipating.

Generally speaking, R-rated comedies fall off on Saturday since younger moviegoers, the target audience for such fare, are more prone to turn out on Friday.

The Campaign, directed by Jay Roach, was unique in several respects.

While it dropped 7 percent on average across the nation, it overperformed in two markets on Saturday as Republican contender Mitt Romney tapped Paul Ryan to be his vice presidential running mate -- Boston, Romney's hometown, and Washington, D.C. ground zero for politics. The film was up 2 percent in Boston, and flat in the nation's capital.
