In case all of the managers shall fail to attend at the same time and place appointed for holding such poll or shall refuse or fail to act or in case no manager has been appointed for such poll, it shall be lawful for the voters present at the precinct voting place on that day to appoint from among the qualified voters of such precinct or club the managers to act as managers in the place and stead of the absent managers, and any one of the managers so appointed shall administer the oath to the other managers. But if the duly appointed managers attend in a reasonable time, they shall take charge of and conduct the election.
