Factions in the Libertarian Party (United States)

Content sourced from Wikipedia, licensed under CC BY-SA 3.0.

The Libertarian Party in the United States includes several factions, and people sometimes describe them as left or right, though many libertarians reject those labels. Notable caucuses today include the Mises Caucus (paleolibertarian), the Classical Liberal Caucus (traditionalist and more left-leaning), the Radical Caucus (anarcho-capitalist), and the Libertarian Socialist Caucus (left-wing). There are smaller groups like the Pro Life Caucus and Bitcoin Caucus.

Major caucuses
- Mises Caucus: Promotes paleolibertarian ideas, Fusionism, and a more conservative take on libertarianism. Named after economist Ludwig von Mises; has been influential and controversial.
- Classical Liberal Caucus: Advocates classical liberal principles, focuses on policy and professional messaging, and aims to appeal to centrists disillusioned with both major parties.
- Radical Caucus (LPRadicals): Pushes for more radical Libertarian programs, sometimes toward abolition of government functions.
- Libertarian Socialist Caucus: A small left-wing group that wants the party to oppose economic exploitation as a form of aggression.
- Other smaller groups include the Pro Life Caucus and the Bitcoin Caucus.

A quick history
- The party formed in 1971 from classical liberals, minarchists, and anarcho-capitalists.
- The Dallas Accord (1974): A tacit agreement to avoid taking a firm stance on whether the state should exist, so the platform didn’t force a yes or no.
- Debates between anarcho-capitalists and minarchists continued for years.
- Ron Paul’s 1988 Libertarian presidential nomination brought attention to more radical factions; he won the nomination and ran, while some peers preferred Russell Means.
- After 1988, some supporters who favored cultural conservatism left the party or stopped using the term paleolibertarian.
- Post‑9/11, some libertarians supported wars in Afghanistan and Iraq.
- By 2006, the party shortened its platform at the Libertarian National Convention, and the Dallas Accord was seen by many as dead. Some anarcho-capitalists left and formed the Boston Tea Party group (2006–2012).

Recent milestones
- 2020: Spike Cohen became the Libertarian Party’s vice presidential candidate, the first anarcho-capitalist on a Libertarian ticket.
- 2022: The Mises Caucus gained control of the Libertarian National Committee, leading to disaffiliations and splits in several state parties.
- 2022–2024: The Classical Liberal Caucus (launched in 2022) pressed for a center-ground, policy-focused message; it has ties to the Chase Oliver 2024 presidential campaign.
- 2024: The Mises Caucus held significant influence, including the roles of Secretary and Chair on the Libertarian National Committee and many state affiliates. A Colorado ballot dispute involving the party highlighted ongoing tensions.

Other groups and dynamics
- The Radical Caucus and Libertarian Socialist Caucus push different visions of how far libertarian ideals should go—scale of government, markets, and social goals.
- The Pragmatist Caucus was a moderate group connected with Gary Johnson’s campaigns; it dissolved in 2022 after internal controversies linked to other factions.

In short, the Libertarian Party includes a mix of groups with varying ideas about government size, markets, and social policy, and control of the party has shifted between these factions over the years.
