Rent Head of State (2003)

When Washington desperately needs a presidential candidate just weeks before the election, they need someone sure to lose. They pick Mays Gilliam (Chris Rock), an unknown local politician from a down-and-out D.C. neighbourhood, to be their puppet. But if Mays is going to run, he's going to have fun. He's bringing in his brother Mitch (Bernie Mac), a hardcore bail bondsman, as his running mate and running his campaign into party central. Now, Gilliam's gaining in the polls and on his way to making history.
