Political History and Evolution
Established in 1913 following the 1910 census, the 12th district has a long history of political milestones. In 1925, Mary Teresa Norton was elected, becoming the first female Democrat to serve in the United States Congress.
For much of its early history, the district was considered a swing district—an area where the majority party can shift between elections. However, redistricting efforts following the 2000 and 2010 censuses shifted the district's boundaries to include more Democratic-leaning areas. The loss of Republican-leaning portions of Hunterdon and Monmouth counties, combined with the addition of strongly Democratic areas in Middlesex and Union counties, solidified its current Democratic lean.
A significant transition occurred in 2014 when Rush D. Holt Jr. retired. He was succeeded by Bonnie Watson Coleman, who made history as the first African-American woman elected to Congress from New Jersey.
Geographic Reach
Based on the redistricting following the 2020 census, the district spans four counties and 32 municipalities:
