Colorado Revised Statutes Title 31. Government Municipal § 31-10-602. Watchers at municipal elections

Each candidate for office, or interested party in case of an issue, at a municipal election is entitled to appoint some person to act in his behalf in every precinct in which he is a candidate or in which the issue is on the ballot. Such candidate or interested party shall certify the names of the persons so appointed to the clerk on forms provided by the clerk. In case a watcher must leave the polling place, he may designate an alternate to act in his behalf while he is absent, if such alternate is made known to the election judges by an affidavit of the person first named as a watcher.
