Conn. Gen. Stat. § 9-262: Duties of election officials during voting hours.

During the entire period of an election, at least one of the election officials shall be stationed approximately three to four feet from the voting tabulator to regulate the submission of the elector's ballot. The election officials shall also, at such intervals as such officials deem proper or necessary, examine the voting booth to ascertain whether it has been defaced or damaged and to detect the wrongdoer and repair the damage. After the opening of the polls, no election official shall allow any person other than the election officials to pass within the area where the voting booths and voting tabulator are situated, except for the purpose of voting or except as provided in this part. No election official shall remain or permit any person to remain in any position or near any position that would permit him to see or ascertain how an elector votes.
