Contemporary libertarianism in the United States

In the United States, polls (circa 2006) found that the views and voting habits of between 10% and 20%, or more, of voting age Americans might be classified as " fiscally conservative and socially liberal, or libertarian ". This was based on pollsters' and researchers' defining libertarian views as fiscally conservative and socially liberal (based on the common United States meanings of the terms) and against government intervention in economic affairs and for expansion of personal freedoms. In a 2015 Gallup poll, this figure had risen to 27%. A 2015 Reuters poll found that 23% of American voters self-identified as libertarians, including 32% in the 18–29 age group. Through twenty polls on this topic spanning thirteen years, Gallup found that voters who are libertarian on the political spectrum ranged from 17–23% of the United States electorate. However, a 2014 Pew Poll found that 23% of Americans who identify as libertarians have no idea what the word means. In this poll, 11% of respondents both identified as libertarians and understand what the term meant.

In 2001, an American political migration movement, called the Free State Project, was founded to recruit at least 20,000 libertarians to move to a single low-population state (New Hampshire, was selected in 2003) in order to make the state a stronghold for libertarian ideas. As of May 2022, approximately 6,232 participants have moved to New Hampshire for the Free State Project.

2009 saw the rise of the Tea Party movement, an American political movement known for advocating a reduction in the United States national debt and federal budget deficit by reducing government spending and taxes, which had a significant libertarian component despite having contrasts with libertarian values and views in some areas such as free trade, immigration, nationalism and social issues. A 2011 Reason -Rupe poll found that among those who self-identified as Tea Party supporters, 41 percent leaned libertarian and 59 percent socially conservative. Named after the Boston Tea Party, it also contained populist elements. By 2016, Politico noted that the Tea Party movement was essentially completely dead; however, the article noted that the movement seemed to die in part because some of its ideas had been absorbed by the mainstream Republican Party.

In 2012, anti-war and pro- drug liberalization presidential candidates such as Libertarian Republican Ron Paul and Libertarian Party candidate Gary Johnson raised millions of dollars and garnered millions of votes despite opposition to their obtaining ballot access by both Democrats and Republicans. The 2012 Libertarian National Convention saw Johnson and Jim Gray being nominated as the 2012 presidential ticket for the Libertarian Party, resulting in the most successful result for a third-party presidential candidacy since 2000 and the best in the Libertarian Party's history by vote number. Johnson received 1% of the popular vote, amounting to more than 1.2 million votes. Johnson has expressed a desire to win at least 5 percent of the vote so that the Libertarian Party candidates could get equal ballot access and federal funding, thus subsequently ending the two-party system. The 2016 Libertarian National Convention saw Johnson and Bill Weld nominated as the 2016 presidential ticket and resulted in the most successful result for a third-party presidential candidacy since 1996 and the best in the Libertarian Party's history by vote number. Johnson received 3% of the popular vote, amounting to more than 4.3 million votes. Following the 2022 Libertarian National Convention, the Mises Caucus, a paleolibertarian faction, became the dominant faction on the Libertarian National Committee. Right-wing libertarian ideals are also prominent in far-right American militia movement associated with extremist anti-government ideas.

Chicago school of economics economist Milton Friedman made the distinction between being part of the American Libertarian Party and "a libertarian with a small 'l'," where he held libertarian values but belonged to the American Republican Party.
