Notable elections
A number of third party, independent, and write-in candidates have performed well in many U.S. 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.
There have been 20th century governors elected as independents, and
from such parties as Progressive, Reform, Farmer-Labor, Populist, and
Prohibition. There were others in the 19th century.
However, the United States has had a two-party system for over a century. The winner take all system for presidential elections and the single-seat plurality voting system for Congressional elections have over time created the two-party system.
Third party candidates sometimes win elections. For example, such a candidate has won a U.S. Senate election twice (0.6%) since 1990. Sometimes a national officeholder not affiliated with and endorsed by one of the two major parties 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 a third-party candidate in 2006 after leaving the Democratic Party. Currently, there are only two U.S. Senators, Angus King and Bernie Sanders, who are neither Democratic nor Republican, while Representative Justin Amash has joined the Libertarian Party as of April 28, 2020.
Although third party candidates rarely actually win elections, they can
have an effect on them. If they do well, then they are often accused of
having a spoiler effect. Sometimes, they have won votes in the electoral college, as in the 1832 Presidential election.
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. Also, a third party may be used by the voter to cast a protest vote as a form of referendum on an important issue. Third parties may also help voter turnout
by bringing more people to the polls. Third party candidates at the top
of the ticket can help to draw attention to other party candidates down
the ballot, helping them to win local or state office. In 2004 the U.S.
electorate consisted of an estimated 43% registered Democrats and 33%
registered Republicans, with independents and those belonging to other
parties constituting 25%.
The only three U.S. Presidents without a major party affiliation 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 a
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.
Bill Walker of Alaska
was from 2014 to 2018 the only independent Governor in the United
States. He was also the first independent Governor since Alaska became a
state (although not the first third-party governor). In 1998, Jesse
Ventura was elected Governor of Minnesota on the Reform Party ticket.
As of 2019, the only independent U.S. senators are Bernie Sanders of Vermont and Angus King of Maine; both Senators caucus with the Democratic Party. Representative Justin Amash,
originally elected as a Republican, joined the Libertarian Party in
April 2020 after having been an independent, and is currently the only
member of a third party in the House.
Barriers to third party success
Winner-take-all vs. proportional representation
In
winner-take-all (or plurality-take-all), 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 except for Maine and
Nebraska, who in Presidential elections allocate their electoral votes
proportionally based on the popular vote in their respective states, are entirely absent at the national level. 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.
If the candidate fails in the primary and believes he or she has a
chance to win in the general election he or she 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.
Ballot access laws
Nationally, ballot access
laws are the major challenge to third party candidacies. While the
Democratic and Republican parties usually easily obtain ballot access in
all fifty states in every election, third parties often fail to meet
criteria for ballot access, such as registration fees. Or, in many
states, they do not meet petition requirements in which a certain number
of voters must sign a petition for a third party or independent
candidate to gain ballot access. 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
multimillionaire, 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, and 2016 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, took place again in 1976
and have happened in every election since. Third party or independent
candidates have been included in these 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.
Debates in other state and federal elections often exclude
Independent and third party candidates, and the Supreme Court has upheld
such tactics in several cases. The Commission on Presidential Debates (CPD) is a private company. 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 was excluded from the 1996 debates despite his strong showing four years prior. 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 remained in place
for 2004, when as many as 62 million people watched the debates, and has continued being in effect as of 2008.
The 15% criterion, had it been in place, would have prevented Anderson
and Perot from participating in the debates they appeared in.
Major party marginalization
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 third parties
with southern agendas. 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.
