The correct answer is a poll watcher.
A poll watcher is an observer requested by a candidate or a political party to be at a specific polling station.
The poll watchers help promote transparency, openness and fairness during an election. The rules for how poll watchers are picked vary from state to state, each political party and each candidate on the ballot is permitted to have one observer only. Requirements for poll watchers are defined within the state as well, most candidates have to be of 'good moral character' and they have to be approved and identified in advance.
Poll watchers generally have two functions :
- making sure that all votes cast in the election are counted correctly,
- reporting suspected irregularities to local officials.
