This northernmost New Jersey district, which includes parts of Bergen, Passaic, Sussex, and Warren counties, swung blue two years ago.
Four candidates are on the ballot. Democrat Josh Gottheimer, a freshman, is the incumbent. The Republican is John McCann Jr. of Hackensack. James Tosone of Washington Township in Bergen County is the Libertarian candidate. Independent Wendy Goetz of Newton is running under the slogan “Trade, Health, Environment.”
