Candidates, political parties, qualified organization of citizens, and organized proponents and opponents of a ballot proposition may appoint pollwatchers. All pollwatchers must be registered to vote in the State of Illinois and must possess valid credentials.
Pollwatchers are official observers only. They may observe the conduct of the election before, during, and after the polls close. All pollwatchers must present valid credentials upon entering the polling place. The judges of elections are the sole authority in the polling place on election day. No person, except a judge, may handle or touch election supplies and materials.
