If you’ve waited for the sequel to “Talladega Nights,” this is it. Ricky Bobby has changed his name to Cam Brady and been elected to the US Congress. His fuzzy, dim-witted counterpart has morphed from John C. Reilly to Zach Galifianakis.

“The Campaign” is not just hilariously funny, it’s also a clever satire of the US political system and the way we elect candidates. You’ve seen tons of negative ads recently here in St. Louis. Maybe you’ve wondered just how low a candidate would go to slam his opponent? You’ll howl when you see how low in “The Campaign.”

Will Ferrell as Cam Brady is a standard issue congressman who keeps getting re-elected and figures to be run unopposed again this year. But two wealthy brothers who are moguls with political clout (played by Dan Akroyd and John Lithgow) draft a yokel named Marty Huggins to oppose him.

Galifianakis as Huggins is a likeable dweeb, who benefits from a Cam Brady campaign miscue and moves up in the polls. With help from a seasoned campaign manager played by Dylan McDermott, he actually becomes the favorite to win. Then the campaigning goes really negative.

As in “Talladega Nights,” there’s a strong cast of sidemen and women. Jason Sudeikis as Brady’s campaign manager, Brian Cox as Marty’s dad and Sarah Baker as Marty’s wife all turn in good performances. But they are trumped by Karen Maruyama who scores huge laughs as a housekeeper with an interesting way of saying things.

Not everything works in “The Campaign,” but the funny and often outrageous developments will keep you engaged and entertained for the movie’s hour and a half run time. Cast your vote at the box office today.
