Bill, Nicki and Cara Lynn travel to Washington, D.C., where Bill tries to land an endorsement from Congressman Clark Paley while mending things with Nicki. Meanwhile, Margene's on-air triumph is tempered by a case of mistaken identity; Joey goes to extremes to safeguard a secret; and Barb and Sarah hit a young Native American woman with their car.

Pressed by Coburn to state his intentions, Bill gets his family to stage an elaborate rally announcing his candidacy. He isn't so lucky when an audit uncovers insurance discrepancies caused by his multiple wives. To protect his secret and save his candidacy, he ends up asking Don to take the fall, and moves up his announcement by three days.
