Since the 1940s, New Jersey’s county political organizations have designed primary ballots to favor their endorsed candidates. Until 2024, 19 of 21 counties used grid systems that placed endorsed candidates in prime spots, known as the “county line,” which influenced the behavior of unsuspecting voters. In 2024, Senate candidate Andy Kim challenged this system in court and won a temporary injunction, leading to a more democratic “office block” layout. The film Down the Line investigates the problems associated with the county line design, exploring the system’s manipulative intent and results and its impact on New Jersey’s political landscape.
