New Jersey's 12th congressional district is represented by Democrat Bonnie Watson Coleman, who has served in Congress since 2015. The district is known for its research centers and educational institutions such as Princeton University, Rider University, The College of New Jersey, Institute for Advanced Study, Johnson & Johnson and Bristol-Myers Squibb. The district is primarily suburban in character, covering portions of Mercer, Somerset, Union, and Middlesex counties, although the district contains the state capital of Trenton as well as the smaller city of Plainfield.

History

The 12th congressional district (together with the 11th district) was created starting with the 63rd United States Congress in 1913, based on redistricting following the 1910 United States census. Historically, the 12th and its predecessors had been a swing district. However, redistricting following the 2000 United States census gave the district a somewhat bluer hue than its predecessor. It absorbed most of Trenton, along with a number of other municipalities. Since then, the 12th has become a Democratic-leaning district, as measured by the Cook PVI.^[3]

The redistricting made second-term Democrat Rush D. Holt Jr. considerably more secure; he had narrowly defeated freshman Republican Michael Pappas in 1998, and had only held on to his seat against Dick Zimmer who represented the district from 1991 to 1997, by 651 votes in 2000. In 2002, despite an expensive challenge from former New Jersey Secretary of State Buster Soaries, Holt was re-elected with 61% of the vote.

The district became even more Democratic after redistricting following the 2010 census, as it lost its share of Republican-leaning Hunterdon County and Monmouth County, while being pushed further into strongly Democratic Middlesex County and gaining the overwhelmingly Democratic Union County town of Plainfield, as well as the portion of Trenton that it had not absorbed in the previous redistricting. Holt retired in 2014 and was succeeded by State Assembly Majority Leader Bonnie Watson Coleman, making her the first African-American woman elected to Congress from New Jersey.
