Voting trends[edit]

The present 12th Congressional District is a Democratic-leaning district, as measured by the Cook PVI.[1] This along with an incumbent Democratic Congressman, has led the Republicans to not target the 12th since the election of 2002.

In the redistricting following the United States Census, 2000, several municipalities (with histories of supporting Democratic candidates) were added to the 12th. In 2002, despite an expensive challenge from former New Jersey Secretary of State Buster Soaries, Rush Holt was re-elected with 61%.

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%).
