The 18th District includes seven communities in Middlesex County: East Brunswick, Edison, Helmetta, Highland Park, Metuchen, South Plainfield, and South River.
This has been considered a safe Democratic district, with 43 percent of voters registered as Democrats and only 15 percent Republicans. Virtually all other voters in the district are unaffiliated.
Democrats represent the district. Both Assembly members are seeking re-election: Nancy Pinkin, a former East Brunswick councilwoman, and Robert Karabinchak of Edison.
The Republican slate consists of Robert A. Benvigenga Jr. of South Plainfield and Jeffrey R. Brown of East Brunswick.
