New Hampshire is often noted for its moderate politics (especially in relation to strongly Democratic neighboring states) and its status as a prominent swing state. Voters predominantly selected Republicans for national office during the 19th and 20th centuries until 1992. Since then, the state has been considered as a swing state. Since 2006, control of the state legislature and New Hampshire's congressional seats have switched back and forth between Republicans and Democrats. However, while southern New Hampshire is noted for its moderate views, northern New Hampshire tends towards hardline conservative politics.
Due to its large state legislature, the annual town meetings in most communities, and the prominence of its presidential primary every four years, New Hampshire has been noted for its high level of political participation and retail politics.[clarification needed] Some have called politics the "state sport."
Historically, New Hampshire was a conservative state and regularly voted Republican, though Coös County, Strafford County, and Hillsborough County leaning Democratic before the 1970s. Some sources trace the founding of the Republican Party to the town of Exeter in 1853. Prior to 1992, New Hampshire had only strayed from the Republican Party for three presidential candidates—Woodrow Wilson, Franklin D. Roosevelt and Lyndon B. Johnson. The state voted for Presidents Richard Nixon and Ronald Reagan twice by overwhelming majorities.
Beginning in 1992, New Hampshire became a swing state in both national and local elections. The state supported Democrats Bill Clinton in 1992 and 1996, John Kerry in 2004, Barack Obama in 2008 and 2012, Hillary Clinton in 2016 and Joe Biden in 2020. Among the states that George W. Bush won in the 2000 election, it was the only one to go Democratic in the 2004 election. The state elected two Democratic governors during this period. State Senator Jeanne Shaheen was elected governor in 1996, 1998, and 2000, and following Republican Craig Benson's win in 2002, Democrat John Lynch flipped the seat in 2004.
In 2006, Democrats won both congressional seats (electing Carol Shea-Porter in the 1st district and Paul Hodes in the 2nd district), re-elected Governor John Lynch, and gained a majority on the Executive Council and in both houses of the legislature for the first time since 1911. Democrats had not held both the legislature and the governorship since 1874. Neither U.S. Senate seat was up for a vote in 2006. In 2008, Democrats retained their majorities, governorship, and congressional seats; and former governor Jeanne Shaheen defeated incumbent Republican John E. Sununu for the U.S. Senate in a rematch of the 2002 contest. At the end of the 2008 election cycle, voters registered Democratic outnumbered those registered Republican.
A 2006 University of New Hampshire survey found that New Hampshire residents who had moved to the state from Massachusetts were mostly Republican. The influx of new Republican voters from Massachusetts has resulted in Republican strongholds in the Boston exurban border towns of Hillsborough and Rockingham counties, while other areas have become increasingly Democratic. The study indicated that immigrants from states other than Massachusetts tended to lean Democratic.
In the 2010 midterm elections, New Hampshire voted out both of its Democratic members in the House of Representatives in favor of Republicans. Republicans also won control of both chambers of the State House by veto-proof majorities, while Governor John Lynch won an unprecedented fourth term.
Two years later, in the 2012 elections, New Hampshire voted out both of its Republican members in the House of Representatives in favor of Democrats. At the same time, voters returned Democrats to the majority in the State House of Representatives, while Republicans held on to a narrow 13-11 majority in the State Senate, despite losing the popular vote. Democrat Maggie Hassan won the 2012 gubernatorial election with a 12% margin of victory, with 54.6% of the vote in the gubernatorial election, becoming the first Democrat to succeed another Democrat as Governor of New Hampshire since 1854.
However, Republicans gained control of the State House in 2014, and in 2016 elections, Republican Executive Councilor Chris Sununu was elected as Governor, giving Republicans full control over state government. However, the state narrowly went to Democrat Hillary Clinton over Republican Donald Trump in that year's presidential election, while Democratic governor Maggie Hassan defeated incumbent Republican Kelly Ayotte to join Senator Jeanne Shaheen and Representatives Carol Shea-Porter and Ann McLane Kuster to make the entire congressional delegation represented by the Democratic party.
In the 2018 midterm elections, both chambers of the state legislature returned to Democratic control, while Sununu was reelected as governor, resulting in divided government.
While New Hampshire Democrats retained their seats in 2020 federal elections, Republicans regained the majority in the state’s Senate, House of Representatives and Executive Council. New Hampshire’s incumbent Republican Gov. Chris Sununu also won election to his third term in office against Democrat Dan Feltes. This election signaled Republican strength on a state level, flipping the Senate from a 14-10 Democratic majority to a 14-10 Republican majority. The house flipped to the GOP with 213 Republicans and 187 Democrats.
Due to New Hampshire's large legislature and the state's history of volunteerism, women have held more political positions in the state than in many others. Since 1975, women have made up at least one-quarter of the state legislature.
The 2008 elections resulted in women holding the majority of seats (13 of the 24) in the New Hampshire Senate, a first for any legislative body in the United States.
Following the 2012 elections, New Hampshire had the first all-female congressional delegation in the country, when Carol Shea-Porter and Ann McLane Kuster were elected to the House of Representatives, joining Senators Jeanne Shaheen and Kelly Ayotte, who had been elected in 2008 and 2010, respectively. The 2012 election also saw New Hampshire elect its second female governor, Maggie Hassan.
Following the 2016 elections, New Hampshire had the first all-female, all-Democratic delegation in the country, when Maggie Hassan defeated incumbent Republican senator Kelly Ayotte in the New Hampshire senate race. Hassan serves alongside Democratic senator Jeanne Shaheen. In the US House, Carol Shea-Porter, a Democrat, defeated incumbent Representative Frank Guinta to represent the 1st Congressional District in New Hampshire again and serving alongside Representative Ann McLane Kuster, a Democrat, who won re-election to represent the 2nd Congressional District.
New Hampshire has elected two women as Governor, Jeanne Shaheen and Maggie Hassan. A third, Vesta M. Roy, was acting Governor for seven days after the previous Governor fell ill and died.
Same-sex marriage became legal in New Hampshire on January 1, 2010, replacing civil unions, which had become legal on January 1, 2008. In doing so, New Hampshire became the first state to recognize same-sex marriage entirely through the legislative process.
After winning veto-proof majorities in both houses of the state legislature in 2010, the Republican leadership in the House attempted to repeal New Hampshire's same-sex marriage law. On March 21, 2012, however, the House defeated the repeal bill on a vote of 211 to 116.
Democrat Maggie Hassan, a supporter of same-sex marriage, ran against the legislature's record and won election as governor in November 2012 and Democrats took control of the House.
New Hampshire has also been noted for its libertarian tendencies, with its history of social libertarianism and fiscal restraint. Residents and politicians alike perennially provide resistance to proposed seat-belt and motorcycle-helmet laws. Automobile insurance is optional under normal circumstances.
The state motto of "Live Free or Die" is another political touchstone. In 2006, when welcome signs at the border began to display the marketing slogan, "You're Going to Love It Here," a firestorm erupted and Governor John Lynch acceded to a privately financed effort to erect new signs bearing the state motto. In 1997, a comparable firestorm had greeted a new issue of car license plates on which the motto was printed rather than embossed; the design was promptly changed to increase the size of the motto. (However, the U.S. Supreme Court had ruled in 1977 that those who object to the motto may tape over or cover up the words, either partially or completely.)
When Senator Judd Gregg included an earmark in the REAL ID Act to compensate New Hampshire for being the first state to implement the Act in 2007, the state legislature enacted a law calling the Act "contrary and repugnant to" the state and federal Bill of Rights and prohibiting the state executive branch from implementing it.
New Hampshire's libertarian reputation led the Free State Project to select it by vote for a mass in-migration. The Free State Project emphasizes decentralized decision making, encouraging new movers and prior residents of New Hampshire to participate in a way the individual mover deems most appropriate. For example, as of 2017, there were 17 Free Staters elected to the New Hampshire House of Representatives, and in 2021, the New Hampshire Liberty Alliance, which ranks bills and elected representatives based on their adherence to what they see as libertarian principles, scored 150 representatives as "A-" or above rated representatives. Participants also engage with other like-minded activist groups such as Rebuild New Hampshire,  Young Americans for Liberty, and Americans for Prosperity.  As of April 2022, approximately 6,232 participants have moved to New Hampshire for the Free State Project. Many of those who have run have not made their affiliation with the Free State Project a prominent feature of their campaigns. The Free State Project has met with opposition not only from Democrats, but also from many within the Republican Party, the party in which most Free State-affiliated candidates have run.
Some Free Staters have conducted acts of civil disobedience to demonstrate their opposition to what they call "victimless crimes." Free Keene, a group of Free Staters in that city, has attracted particular attention to the high number of acts of civil disobedience, which have often been considered confrontational, and their effect on Keene's image and economy. In recent years, a group of Free Keene members, calling themselves "Robin Hooders" have fed expired parking meters and videotaped their encounters with the parking enforcement officers, suggesting that the officers should refrain from writing tickets and get a different job. The close encounters with the "Robin Hooders" resulted in one officer resigning his position and a lawsuit filed by the City of Keene citing harassment of their employees. In December 2013, the judge overseeing the case dismissed the city's arguments against the "Robin Hooders" on first amendment grounds, citing the public sidewalks' role as a traditional public forum.
Taxation is a perennial electoral issue in New Hampshire, where there is strong opposition to "broad-based" taxes. Their absence is not absolute; there is a 9% tax on meals and rentals, and a 5% income tax on dividends and interest; moreover, the state's 8.5% Business Enterprise Tax is essentially an income tax on sole proprietors. However, candidates for legislature and Governor are routinely asked to take "The Pledge" against broad-based taxes.
The property tax is the source of nearly all municipal revenue. It is "broad-based" (affecting even renters, indirectly) but does not attract the same controversy because municipal expenditures are voted locally, typically by Town Meeting, in which every voter can participate.
In 2002, in response to court-ordered statewide equalization of education funding (see the Claremont Decision), New Hampshire instituted a statewide property tax. The tax is lower than the amount already assessed by municipalities, it is collected by municipalities, and is essentially returned to them, though legislative adjustments create "donor towns" and "recipient towns." Each new legislature has considered changes to the distribution formula.
Taxes that are not "broad-based" (that is, that residents could avoid paying) have not aroused comparable controversy. For example, the meals and rentals tax disproportionately impacts tourists and visitors, who do not vote. Recent legislatures have covered increased spending with increases in sin taxes, tolls, and filing fees. Some feel it would be simpler and fairer to enact a broad-based tax; in 2008, various Town Meetings considered citizen petitions against "The Pledge." In particular, the property tax is seen as unfairly impacting the poor and especially retirees. Advocates of a state broad-based tax say it would permit higher state payments to municipalities, enabling them to lower property taxes. The opposing argument is that a new state tax would not change this alleviate local taxes, but would eventually lead to more state spending.
New Hampshire's lower tax burden has also induced contiguous Amesbury and Salisbury, Massachusetts, and not-nearly-contiguous Killington, Vermont in 2004 and 2005, to petition to become part of New Hampshire. This reflected local discontent with restrictions on liberty or profitability, rather than any expectation that their own states plus the U.S. Congress would grant the necessary permission.
