Plot
In a presidential election set in an alternate 2008, Ernest "Bud" Johnson (Kevin Costner) is a dimwitted, jobless, apolitical man from Texico, New Mexico, coaxed by his twelve-year-old daughter Molly (Madeline Carroll) to take more of a serious approach to life. Molly runs the household and sees an opportunity on election day to energize her father.
Frustrated by Bud’s apathy toward voting, Molly sneaks into her local polling place and tries to vote on behalf of Bud. However, because the voting machines are unplugged, the ballot is registered, but no decision is indicated on which candidate receives the vote. As the election is close, Bud's vote becomes critical to allocating New Mexico's electoral college votes.
