|New Jersey's 12th congressional district|
District map as of 2013
New Jersey's Twelfth Congressional district is represented by Democrat Bonnie Watson Coleman. 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.
Historically, the 12th and its predecessors had been a swing district. However, redistricting following the United States Census, 2000 gave the district a somewhat bluer hue than its predecessor. It absorbed most of Trenton, along with a number of other municipalities.
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 2002, despite an expensive challenge from former New Jersey Secretary of State Buster Soaries, Holt was re-elected with 61%.
Since then, the 12th has trended into a Democratic-leaning district, as measured by the Cook PVI. In 2004, Holt was re-elected over real estate executive Bill Spadea (59-41%) and again in 2006 over former Helmetta Council President Joseph Sinagra (65-35%).
In 2008, Holt defeated Holmdel Township Deputy Mayor Alan Bateman (62-36%).
In 2010, while Democrats suffered huge House loses, Holt defeated Princeton venture capitalist Scott Sipprelle and Independent Kenneth J. Cody (53-46-1%).
Holt retired in 2014, and was succeeded by State Assembly Majority Leader Bonnie Watson Coleman.
A change was made by the New Jersey Redistricting Commission that took effect in January 2013 with the 113th United States Congress, based on the results of the 2010 United States Census. The district currently contains portions of four counties and 31 municipalities:
Mercer County (10)

Somerset County (4)
Union County (3)
