2012 United States presidential election in New Jersey

The 2012 United States presidential election in New Jersey took place on November 6, 2012, as part of the 2012 United States presidential election in which all 50 states plus the District of Columbia participated. Voters in the state chose 14 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan.

Due to the difficulty of getting to polling places because of the damage caused by Hurricane Sandy, voters who were displaced were allowed to vote electronically. Officials were not prepared for the 15 minutes that it took to validate each request, and were deluged by voters who were not displaced asking to vote electronically, so voting was extended until Friday, November 9, at 8 PM. Requests had to be submitted by 5 PM. It is likely that Obama's response to the hurricane, approved by 77% of Obama voters (with 8% disapproving and 15% unsure) and 44% (with 21% disapproving and 35% unsure) of Romney's voters, boosted his performance in New Jersey, which was hit hard by the superstorm.

New Jersey was won by President Obama with 58.25% of the vote to Romney's 40.50%, a 17.75% margin of victory, an increase from 15.53% in 2008. New Jersey was 1 of just 6 states to swing in President Obama's favor between 2008 and 2012, giving him the largest vote share for a Democratic presidential nominee in the state since Lyndon Johnson's 1964. Obama won over many municipalities in northeastern New Jersey that voted Republican in 2008.

As of the 2020 presidential election, this is the last time a Democrat has won Salem County.

Analysis
New Jersey was one of just six states that voted more Democratic in 2012 than it had in 2008. In 2008, Obama won the state by roughly 602,000 votes, whereas in 2012, this margin increased to about 648,000 votes. Obama's increased statewide margin owed itself to larger Democratic margins in several central and northern counties. In Middlesex, Hudson, Passaic, and Union Counties collectively, Obama netted nearly 45,000 additional votes compared to 2008. Outside of these four counties, most others in the state had comparable margins to 2008.

Turnout patterns relative to 2008 arguably helped Obama increase his statewide margin. Every county cast fewer votes in 2012 than in 2008, but not uniformly so. Perhaps due to the effects of Hurricane Sandy, conservative Monmouth County saw the largest percentage decrease in votes cast from 2008, with Ocean County also witnessing a substantial decline in votes cast. In the northwestern part of the state, strongly Republican Sussex and Warren County experienced moderately lower turnout. In terms of raw votes cast, Passaic County, which is strongly Democratic, came closest to its 2008 figures, with just 5,000 fewer votes cast in 2012 than in 2008.

Obama's improved performance was quite unusual as his performance worsened in most other areas of the nation (particularly the Midwest and Rust Belt). It is likely this was due to his widely approved response to Hurricane Sandy, which had a devastating effect on the state, causing two million households to lose power, destroying 346,000 homes, and causing blockades on bridges and roads for up to two weeks. Obama's response to the so-called superstorm also likely contributed to his improved performance. According to a poll conducted by ABC News and The Washington Post, not only did 77% of Obama's voters approve of his handling of the storm (with 8% disapproving and 15% unsure), he also received a plurality amongst Romney voters, with 44% approving of his handling, 21% disapproving, and 35% unsure. Another poll by the Pew Research Center found that 67% of registered voters approved of Obama's response with only 15% disapproving. Chris Christie, the state's Republican governor called Obama's response to the hurricane "outstanding" and praised him for his frequent coordination with the New Jersey government, potentially boosted his popularity amongst Republican voters.
