Take your friend to the polling place he should go to and have them check the rolls for his name and if it's not there tell them that he wants a
Provisional Ballot.
Provisional voting is one of the election reform measures Secretary Blunt initiated in Missouri, in order to guarantee every qualified and registered voter has the opportunity to vote on Election Day.
When voters arrive at the polling place on Election Day, the election judges check the poll book, a list of all of the jurisdiction's registered voters, to confirm that the voter is properly registered and at the correct polling place. Prior to provisional voting, if a person's name was not in the poll book they were not allowed to vote. With provisional voting, a voter whose name is not found in the poll book on Election Day is given a provisional ballot.
Provisional ballots are distinguished from regular ballots so that the election authority can later investigate the provisional voter's registration status. www.sos.mo.gov/firstvote/students/voting_faq.asp
