At first Brady does not take Huggins seriously as a running mate because of his quirky nature. However, Brady, decides to create a film that shows Huggins in many different situations that make him look unintelligent. In response, Huggins publicly asks Brady to recite the Lord's Prayer. Brady fails to recite it horribly and is humiliated. Because of Brady's previous escapades, not being able to recite the Lord's Prayer causes him to decline in popularity.
In attempts to save his career, Brady begins running smear campaigns against Huggins. At first, Huggins doesn't want to retaliate for moral reasons, but is convinced by his campaign manager, Tim Wattley, to create television ads that will hurt Brady's reputation. Huggins crosses the line when he films Brady's son calling him "dad" and airs it. Brady, wanting to humiliate Huggins worse, sleeps with Huggin's wife and films it, then proceeds to air the tape publicly.
Huggins eventually learns of the Motch brother's plans and tells him that he will be no part of it. The Motch brothers take away their funding and give it to Brady. Huggins makes peace with his family, which has been torn apart by the events of the campaign, and then reminds Brady who he is. Brady realizes that the way he has been campaigning and treating his position has been wrong, and then withdraws from the race. Brady and Huggins come to terms with one another, and Huggins promotes Brady to chief of staff. The two expose the Motch brothers while working as a team.
You wouldn't peg Zach Galifianakis and Will Ferrell for readers of "50 Shades of Grey," but in this video that's exactly what they're doing. And it looks like they're actually kind of enjoying it.
