New Jersey Statutes Title 19. Elections 19 § 34-6

a. If a person shall on election day tamper, deface or interfere with any polling booth or obstruct the entrance to any polling place, or obstruct or interfere with any voter, or loiter in or near the polling place, or, with the purpose to obstruct or interfere with any voter or to unduly delay other voters from voting, spend an inordinate amount of time in the polling booth, or do any electioneering within any polling place or within one hundred feet thereof, he shall be guilty of a crime of the third degree.

b. This section shall not be construed to prohibit a minor from entering a polling place on the day of an election to vote in a simulated election at that polling place, or persons from supervising or working at a polling place in a simulated election in which minors vote, provided that the county board of elections has determined that the polling place can accommodate simulated election activities without interfering with the orderly conduct of the official voting process.
