It's not Obama versus Romney, but the political battle between all-star comedians Will Ferrell and Zach Galifianakis is shaping up to be a can't-miss affair all the same.

The "Anchorman" and "Hangover" actors join forces in "The Campaign," Jay Roach's new comedy about an election race between two radically different politicans. Ferrell plays long-term congressman Cam Brady, who finds his normally unopposed position threatened after a major public gaffe. His rival for reelection is Marty Huggins, a tourism director without much of a clue but enough of the right people behind his back. What ensues is a cut-throat, gut-busting showdown between two of the funniest guys in show business — a premise that would be well worth the price of admission on its own, and is only helped further by a slew of great reviews.

Read on for a selection of reviews for "The Campaign," in theaters now.

The Set-Up
"Will Ferrell seems to channel the hair, accent and wandering penis of John Edwards to play Cam Brady, a Democratic congressional incumbent from North Carolina in 'The Campaign.' Cam, who boasts--as Edwards was wont to do--that his father worked with his hands (although in this case 'as a stylist for Vidal Sassoon' rather than as a mill worker) is running for his fifth term. He's unopposed as usual until a pair of nefarious businessmen (Dan Aykroyd and John Lithgow) with plans to sell the district to the Chinese put forward a puppet candidate, Republican Marty Huggins (Zach Galifianakis). The race is on." --Mary Pols, Time Entertainment

The Ferrell Factor
"The movie begins seeming like it might be yet another shooting-fish-in-a-barrel fest, as fresh politico Ferrell, sporting a heavy Southern accent, learns to string the words 'America,' 'Jesus' and 'freedom' together for his election-winning advantage. But with a few terms in Congress under his belt, Ferrell's Cam Brady becomes an excess-loving, clueless corrupt boob who makes Ron Burgundy look like Edward R. Murrow. ... So, yes, Will Ferrell, all is forgiven after the botch that was 'Casa De Mi Padre.' And in fact this may be the best movie, comedic or dramatic, that you've made yet." --Glenn Kenny, MSN Movies

The One-Man Wolf-Pack
"While both leads consistently hit the right sound bites, I give the edge to Galifianakis. His Marty is a comic gold mine, a Mr. Rogers type who transforms into a fiercely determined rival. 'The Hangover' sensation, who was so good in the underseen 'It's Kind of a Funny Story,' makes Marty absurdly likable, proving he's a fine actor and comedian -- just like Ferrell." --Randy Myers, San Jose Mercury

The Negative Spin
"'The Campaign' does flirt with satire in the form of the Motch brothers (aced by Dan Aykroyd and John Lithgow), billionaire right-wing power brokers (modeled on the Koch brothers) who conspire to insource cheap Chinese labor to North Carolina. But the jokes never go deep, the toothless bites at the system leave no marks. It's only the wild-card energy of Ferrell and Galifianakis that keeps you on the ticket." --Peter Travers, RollingStone.com

The Final Word
"[There's] a genius behind the silliness in 'The Campaign,' in that a go-for-broke comedy might really be the only way to deal with the reality of modern politics. The minute you start thinking that no candidate as loony as Marty Huggins would be successfully backed by some shark-like Washington investors, you just know an identical guy will be the big new success story after the next midterm elections. Roach knows as well as anyone that politics is a dirty and ridiculous business, and 'The Campaign' unveils that truth with enough humor to make it bearable -- and hilarious." --Katey Rich, CinemaBlend.com
