Third party, or minor party, is a term used in the United States' two-party system for political parties other than the Democratic and Republican parties. The Electoral College for presidential elections and the plurality voting system for most other elections have established a two-party system in American politics. Third parties are most often encountered in presidential elections and while third-party candidates rarely win elections, they can have an effect on them through vote splitting and other impacts.

With few exceptions, the U.S. system has two major parties which have won, on average, 98% of all state and federal seats. According to Duverger's law two main political parties emerge in political systems with plurality voting in single-member districts. In this case, votes for minor parties can potentially be regarded as splitting votes away from the most similar major party. Third party vote splitting exceeded a president's margin of victory in three elections: 1844, 2000, and 2016.

There have only been a few rare elections where a minor party was competitive with the major parties, occasionally replacing one of the major parties in the 19th century. No third-party candidate has won the presidency since the Republican Party became the second major party in 1856 and won in 1860. Since then, a third-party candidate won states in five elections: 1892, 1912, 1924, 1948, and 1968. 1992 was the last time a third-party candidate placed second in any state, and 1996 was the last time a third-party candidate got over 5% of the vote nationally.

Notable exceptions

Greens, Libertarians, and others have elected state legislators and local officials. The Socialist Party elected hundreds of local officials in 169 cities in 33 states by 1912, including Milwaukee, Wisconsin; New Haven, Connecticut; Reading, Pennsylvania; and Schenectady, New York. There have been governors elected as independents, and from such parties as Progressive, Reform, Farmer-Labor, Populist, and Prohibition. After losing a Republican primary in 2010, Bill Walker of Alaska won a single term in 2014 as an independent by joining forces with the Democratic nominee. In 1998, wrestler Jesse Ventura was elected governor of Minnesota on the Reform Party ticket.

Sometimes a national officeholder that is not a member of any party is elected. Previously, Senator Lisa Murkowski won re-election in 2010 as a write-in candidate after losing the Republican primary to a Tea party candidate, and Senator Joe Lieberman ran and won reelection to the Senate as an "Independent Democrat" in 2006 after losing the Democratic primary. As of 2025, there are only two U.S. senators, Angus King and Bernie Sanders, who identify as Independent and both caucus with the Democrats.

The last time a third-party candidate carried any states in a presidential race was George Wallace in 1968, while the last third-party candidate to finish runner-up or greater was former president Teddy Roosevelt's 2nd-place finish on the Bull Moose Party ticket in 1912. In Presidential elections, the majority requirement of the Electoral College, and the Constitutional provision for the House of Representatives to decide the election if no candidate receives a majority, serves as a further disincentive to third party candidacies.

In the United States, if an interest group is at odds with its traditional party, it has the option of running sympathetic candidates in primaries. Candidates failing in the primary may form or join a third party. Because of the difficulties third parties face in gaining any representation, third parties tend to exist to promote a specific issue or personality. Often, the intent is to force national public attention on such an issue. Then, one or both of the major parties may rise to commit for or against the matter at hand, or at least weigh in. H. Ross Perot eventually founded a third party, the Reform Party, to support his 1996 campaign. In 1912, Theodore Roosevelt made a spirited run for the presidency on the Progressive Party ticket, but he never made any efforts to help Progressive congressional candidates in 1914, and in the 1916 election, he supported the Republicans.

Micah Sifry argues that despite years of discontentment with the two major parties in the United States, third parties should try to arise organically at the local level in places where ranked-choice voting and other more democratic systems can build momentum, rather than starting with the presidency, a proposition incredibly unlikely to succeed. However, this ignores that in some states a third party is required to have a presidential candidate in order to also run local level candidates.

Spoiler effect

Strategic voting often leads to a third-party that underperforms its poll numbers with voters wanting to make sure their vote helps determine the winner. In response, some third-party candidates express ambivalence about which major party they prefer and their possible role as spoiler or deny the possibility. The US presidential elections most consistently cited as having been spoiled by third-party candidates are 1844, 2000, and 2016.

Ballot access laws

Nationally, ballot access laws require candidates to pay registration fees and provide signatures if a party has not garnered a certain percentage of votes in previous elections. In recent presidential elections, Ross Perot appeared on all 50 state ballots as an independent in 1992 and the candidate of the Reform Party in 1996. Perot, a billionaire, was able to provide significant funds for his campaigns. Patrick Buchanan appeared on all 50 state ballots in the 2000 election, largely on the basis of Perot's performance as the Reform Party's candidate four years prior. The Libertarian Party has appeared on the ballot in at least 46 states in every election since 1980, except for 1984 when David Bergland gained access in only 36 states. In 1980, 1992, 1996, 2016, and 2020 the party made the ballot in all 50 states and D.C. The Green Party gained access to 44 state ballots in 2000 but only 27 in 2004. The Constitution Party appeared on 42 state ballots in 2004. Ralph Nader, running as an independent in 2004, appeared on 34 state ballots. In 2008, Nader appeared on 45 state ballots and the D.C. ballot.

Debate rules

Presidential debates between the nominees of the two major parties first occurred in 1960, then after three cycles without debates, resumed in 1976. Third party or independent candidates have been in debates in only two cycles. Ronald Reagan and John Anderson debated in 1980, but incumbent President Carter refused to appear with Anderson, and Anderson was excluded from the subsequent debate between Reagan and Carter. Independent Ross Perot was included in all three of the debates with Republican George H. W. Bush and Democrat Bill Clinton in 1992, largely at the behest of the Bush campaign. His participation helped Perot climb from 7% before the debates to 19% on Election Day.

Perot did not participate in the 1996 debates. In 2000, revised debate access rules made it even harder for third-party candidates to gain access by stipulating that, besides being on enough state ballots to win an Electoral College majority, debate participants must clear 15% in pre-debate opinion polls. This rule has been in effect since 2000. The 15% criterion, had it been in place, would have prevented Anderson and Perot from participating in the debates in which they appeared. Debates in other state and federal elections often exclude independent and third-party candidates, and the Supreme Court has upheld this practice in several cases. The Commission on Presidential Debates (CPD) is a private company. In cases with an extreme minor candidate, not changing positions can help to reframe the more competitive candidate as moderate, helping to attract the most valuable swing voters from their top competitor while losing some voters on the extreme to the less competitive minor candidate.

In 2023 and 2024, Robert F. Kennedy Jr. initially polled higher than any third-party presidential candidate since Ross Perot in the 1992 and 1996 elections. As Democrat Joe Biden withdrew from the race and the election grew closer, his poll numbers and notoriety would drop drastically.
