When their housemate is hauled off to prison, three Republican senators sharing a row house in Washington, D.C., find themselves in need of a new boarder. Enter Florida freshman Andy Guzman, who joins the guys as they battle primary challenges, party filibusters and the possibility of a junket to Afghanistan. Gil John Biggs suddenly finds himself facing a real opponent in a primary, which means he may actually have to do something — like go to Kabul, where a group of soldiers from his North Carolina district has just been deployed. Louis Laffer is facing a challenge of his own, but his opponent is questioning Louis’ manhood while playing up his own rugged outdoorsman persona in Nevada. Robert Bettancourt, the gentleman from Pennsylvania, suddenly finds he’s about to be indicted. Meanwhile, Andy brings a gorgeous “contributor” to check out his new bedroom.
