Third party (U.S. politics)

Third party (or minor party) is a term used in the United States for political parties other than the two major parties (the Republican and Democratic parties).

Third parties are most often encountered in presidential nominations. No third-party candidate has won the presidency since the Republican Party became a major party in the mid-19th century. Since that time, only in five elections (1892, 1912, 1924, 1948, and 1968) has a third-party candidate carried any states.^[1]

Competitiveness

With few exceptions,^[2] the U.S. system has two major parties which have won, on average, 98% of all state and federal seats.^[3] 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.^[4][5] The winner take all system for presidential elections and the single-seat plurality voting system for Congressional elections have over time helped establish the two-party system (see Duverger's law). Although third-party candidates rarely win elections, they can have an effect on them through vote splitting and other impacts.

Notable exceptions

Main articles: List of third party and independent performances in United States elections and List of third-party performances in United States presidential elections

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.^[6] There have been governors elected as independents, and from such parties as Progressive, Reform, Farmer-Labor, Populist, and Prohibition. Recent examples include Bill Walker of Alaska who was, from 2014 to 2018, the only independent governor at the time, and wrestler Jesse Ventura who was elected governor of Minnesota on the Reform Party ticket in 1998.^[7]

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 and not as the Republican nominee, and Senator Joe Lieberman ran and won as an independent candidate in 2006 after leaving the Democratic Party.^[8][9] As of 2023, there are only three U.S. senators, Angus King, Bernie Sanders and Kyrsten Sinema, who are neither Democratic nor Republican (all identify as Independent).^[10]

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.^[11] The only three U.S. presidents without a major party affiliation upon election were George Washington, John Tyler, and Andrew Johnson, and only Washington served his entire tenure as an independent. Neither of the other two were ever elected president in their own right, both being vice presidents who ascended to office upon the death of the president, and both became independents because they were unpopular with their parties. John Tyler was elected on the Whig ticket in 1840 with William Henry Harrison, but was expelled by his own party. Johnson was the running mate for Abraham Lincoln, who was reelected on the National Union ticket in 1864; it was a temporary name for the Republican Party.

Barriers to third party success

Winner-take-all vs. proportional representation

See also: Duverger's law

In winner-take-all (or plurality voting), the candidate with the largest number of votes wins, even if the margin of victory is extremely narrow or the proportion of votes received is not a majority. Unlike in proportional representation, runners-up do not gain representation in a first-past-the-post system. In the United States, systems of proportional representation are uncommon, especially above the local level and are entirely absent at the national level (even though states like Maine have introduced systems like ranked choice voting, which ensures that the voice of third party voters is heard in case none of the candidates receives a majority of preferences).^[12] 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, that third parties should try to arise organically at the local level in places where ranked-choice voting and other more democratic systems makes it easier to build momentum, rather than starting with the presidency which would be incredibly unlikely to succeed.^[13]

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^[14] or deny the possibility.^[15] The two US presidential elections most consistently cited as having been spoiled by third-party candidates are 1844 and 2000.^{[16][17][18][19][20]} This phenomenon becomes more controversial when a third-party candidate receives help from supporters of another candidate hoping they play a spoiler role.^[21][22][23]

The Keys to the White House has argued that in a U.S. presidential election a significant third-party or independent campaign damages the incumbent party's candidate more, and increases the challenging party candidate's chance of winning the election^[24] as it suggests public dissatisfaction with the incumbent party's candidate and policies.^{[citation needed]}

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.^[25] 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.^{[citation needed]} His participation helped Perot climb from 7% before the debates to 19% on Election Day.^[26]

Perot did not make the 1996 debates.^[27] 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 continued being in effect as of 2008.^[28][29] 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.^[30]

Major parties adopt third-party platforms

They can draw attention to issues that may be ignored by the majority parties. If such an issue finds acceptance with the voters, one or more of the major parties may adopt the issue into its own party platform. A third-party candidate will sometimes strike a chord with a section of voters in a particular election, bringing an issue to national prominence and amount a significant proportion of the popular vote. Major parties often respond to this by adopting this issue in a subsequent election. After 1968, under President Nixon the Republican Party adopted a "Southern Strategy" to win the support of conservative Democrats opposed to the Civil Rights Movement and resulting legislation and to combat local third parties. This can be seen as a response to the popularity of segregationist candidate George Wallace who gained 13.5% of the popular vote in the 1968 election for the American Independent Party. In 1996, both the Democrats and the Republicans agreed to deficit reduction on the back of Ross Perot's popularity in the 1992 election. This severely undermined Perot's campaign in the 1996 election.

However, changing positions can be costly for a major party. For example, in the US 2000 Presidential election Magee predicts that Gore shifted his positions to the left to account for Nader, which lost him some valuable centrist voters to Bush.^[31] 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.^[32]

Today, as in 1958, ballot access for minor parties and Independents remains convoluted and discriminatory. Though certain state ballot access statutes are better, and a few Supreme Court decisions (Williams v. Rhodes, 393 U.S. 23 (1968), Anderson v. Celebrezze, 460 U.S. 780 (1983)) have been generally favorable, on the whole, the process—and the cumulative burden it places on these federal candidates—may be best described as antagonistic. The jurisprudence of the Court remains hostile to minor party and Independent candidates, and this antipathy can be seen in at least a half dozen cases decided since Nader's article, including Jenness v. Fortson, 403 U.S. 431 (1971), American Party of Tex. v. White, 415 U.S. 767 (1974), Munro v. Socialist Workers Party, 479 U.S. 189 (1986), Burdick v. Takushi, 504 U.S. 428 (1992), and Arkansas Ed. Television Comm'n v. Forbes, 523 U.S. 666 (1998). Justice Rehnquist, for example, writing for a 6–3 divided Court in Timmons v. Twin Cities Area New Party, 520 U.S. 351 (1997), spells out the Court's bias for the "two-party system," even though the word "party" is nowhere to be found in the Constitution. He wrote that "The Constitution permits the Minnesota Legislature to decide that political stability is best served through a healthy two-party system. And while an interest in securing the perceived benefits of a stable two-party system will not justify unreasonably exclusionary restrictions, States need not remove all the many hurdles third parties face in the American political arena today." 520 U.S. 351, 366–67.
