The politics of New England has long been defined by the region's political and cultural history, demographics, economy, and its loyalty to particular U.S. political parties. Within the politics of the United States, New England is sometimes viewed in terms of a single voting bloc. Of the twenty-one congressional districts in New England, twenty are currently represented by Democrats. In the Senate, nine Democrats, two Independents (both of whom caucus with Democrats), and one Republican represent New England. The Democratic candidate has won a plurality of votes in every State in New England in every presidential election since 2004, making the region considerably more Democratic than the rest of the nation.
Same-sex marriage is permitted in all six New England states, with Rhode Island being the final state to legalise the practice in May 2013.  In Maine, it was legalized by the legislature in 2009, but defeated in a referendum (53% voted to ban it versus 47% who voted to legalize it) later the same year. On January 26, 2012, supporters of a ballot initiative to repeal that decision obtained sufficient petition signatures to ensure the initiative appeared on the November 2012 ballot, where the initiative won 53–47.
The national U.S. movement against nuclear power had its roots in New England in the 1970s. In 1974, activist Sam Lovejoy toppled a weather tower at the site of the proposed Montague Nuclear Power Plant in Western Massachusetts.  The movement "reached critical mass" with the arrests at Seabrook Station Nuclear Power Plant on May 1, 1977, when 1,414 anti-nuclear activists from the Clamshell Alliance were arrested at the Seabrook site. Harvey Wasserman, a Clamshell spokesman at Seabrook, and Frances Crowe of Northampton, an American Friends Service Committee member, played key roles in the movement.

The New England states abolished the death penalty for robbery and burglary in the 19th century, before much of the rest of the U.S.A. As of 2012, New Hampshire is the only state in New England that has retained capital punishment.  Although New Hampshire currently has one death row inmate, it has not held an execution since 1939. 
Connecticut and Rhode Island were the only states in the union not to ratify the Eighteenth Amendment to the United States Constitution, also known as prohibition.  Prohibition became the law of the land on January 16, 1919.
Massachusetts passed a ballot initiative (question 3) in the November 2012 election that legalized medical marijuana, effective January 1, 2013. Only people with debilitating diseases such as cancer, Parkinson's disease, or Alzheimer's can obtain a medical marijuana card. Massachusetts became the 18th state in the U.S.A. to legalize the medical use of marijuana.  Similar laws are also in place in four other New England States. 
Same-sex marriage is legal or has been legalized in all of the New England states: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont, as well as in the neighboring state of New York. The New England region has been noted for being the nucleus of the same-sex marriage movement in the United States,  with the region having among the most widespread and earliest legal support of any region. In 2004, Massachusetts became the first state in the United States to legalize same-sex marriage,  to be followed by three more states between October 2008 and June 2009. This followed Vermont being the first-in-the-nation with civil unions in 2000.  Before the 2012 election, California (2008), Iowa (2009), New York (2011) and the District of Columbia (2010) had been the only U.S. jurisdictions outside New England to have performed same-sex marriages, though same-sex marriages in California had been halted following the passage of Proposition 8.
The legalization of same-sex marriage was part of a campaign which began in November 2008, called Six by Twelve, and was organized by the Gay & Lesbian Advocates & Defenders (GLAD) to legalize same-sex marriage in all six New England states by 2012.  
The region holds a number of firsts on same-sex marriage: Vermont was the first state to enact it through legislative means and not because of a judicial ruling,   and Maine was the first state to have a governor sign a same-sex marriage bill that was not the result of a court decision.  Maine's first gay marriage law was repealed through a people's veto, but three years later, on November 6, 2012, the question was put to voters a second time, and Maine became one of three first US states to approve same-sex marriage at the ballot box, along with Washington and Maryland.
With Rhode Island legalizing same sex marriage, all New England states have same-sex marriage. There have been numerous      reasons given for why New England has found such strong legal recognition for same-sex marriages in comparison to the rest of the United States.
There were four targets of the anti-nuclear movement since 1974. As a result, Montague Nuclear was cancelled. Yankee Rowe closed prematurely for engineering inadequacies. Vermont Yankee was closed because it became uncompetitive. Seabrook remains operational.
On February 22, 1934, Sam Lovejoy took a crowbar to the weather-monitoring tower which had been erected at the Montague Nuclear Power Plant site. Lovejoy fell 349 feet (106 m) from the 550 feet (170 m) tower. He turned himself in to the local police. He presented a statement in which he took responsibility for the action. Lovejoy's action galvanized local public opinion against the plant.   The Montague nuclear power plant proposal was canceled in 1980,  after $29 million was spent on the project. 
Seabrook power plant was proposed as a twin-reactor plant in 1972, at an estimated cost of $973 million. It received a commercial license in March 1990 for one reactor which cost $6.5 billion.  Over a period of thirteen years more than 4,000 citizens, many associated with the Clamshell Alliance anti-nuclear group, committed non-violent civil disobedience at Seabrook: 
- August 1, 1976: 200 residents rallied at the future Seabrook Station Nuclear Power Plant site in New Hampshire, and 18 were arrested for criminal trespass. 
- August 22, 1976: 188 activists from New England were arrested at the Seabrook site.  
- May 2, 1977: 1,414 protesters were arrested at Seabrook Station Nuclear Power Plant.    The protesters who were arrested were expected to be "released on their own recognizance", but this did not happen. Instead, they were charged with criminal trespass and asked to post bail ranging from $100 to $500. They refused and were then held in five national guard armories for 12 days. The Seabrook conflict, and role of New Hampshire Governor Meldrim Thomson, received much national media coverage. 
- May 13, 1977: 550 protestors were freed after being detained for thirteen days. 
- June 1978: some 12,000 people attended a protest at Seabrook.  
- May 25–27, 1980: Police use tear gas, riot sticks and dogs to drive 2,000 demonstrators away from the Seabrook site. 
- May 24, 1986: 74 anti-nuclear demonstrators were arrested in protests.  
- October 17, 1988: 84 people were arrested at the Seabrook plant. 
- June 5, 1989: hundreds of demonstrators protested against the plant's first low-power testing, and the police arrested 627 people for trespassing; two state legislators, one from Massachusetts and one from New Hampshire, protested.  
The New England Coalition (NEC) is an educational non-profit organization based in Brattleboro, Vermont. Historically, it has been part of the anti-nuclear movement in the United States.  The NEC is primarily concerned with legal action more than protests. It was involved in both legal action and protests about the Yankee Rowe Nuclear Power Plant prior to its shut down in 1992, and has been involved in legal action and protests over extending the license to operate at the Vermont Yankee Nuclear Power Plant.
In February 2010, the Vermont Senate voted 26 to 4 against allowing the PSB to consider re-certifying the Vermont Yankee Nuclear Plant after 2012, citing radioactive tritium leaks, misstatements in testimony by plant officials, a cooling tower collapse in 2007, and other problems.  In January 2012, Entergy won a court case to invalidate the state's veto power on continued operation. 
There were a number of anti-nuclear protests about Vermont Yankee since the 1970s. These included protests following the Japanese Fukushima nuclear disaster in March 2011 and on the date of the original operating license expiry in March 2012. On August 28, 2013 the company said economic factors, notably the low cost of electricity caused by cheap natural gas, would result in the company's decommissioning the plant in the fourth quarter of 2014.
