The Iowa Caucus campaign already has plenty of real presidential candidates.
Now it's getting a fictional president and another Hollywood celebrity as the politicking heads into the home stretch.
Actor Martin Sheen, who portrayed President Josiah Bartlet in the NBC television drama series "The West Wing," is coming to Iowa on behalf of Democrat Bill Richardson.
