Two-party system
Third parties, meaning a party other than one of the two dominant parties, are possible in two-party systems, but they are often unlikely to exert much influence by gaining control of legislatures or by winning elections. While there are occasional opinions in the media expressed about the possibility of third parties emerging in the United States, for example, political insiders such as the 1980 presidential candidate John Anderson think the chances of one appearing in the early twenty-first century is remote. A report in "The Guardian" suggested that American politics has been "stuck in a two-way fight between Republicans and Democrats" since the Civil War, and that third-party runs had little meaningful success.
Third party (politics)
In U.S. politics, a third party is a political party other than the Democrats or Republicans, such as the Libertarians and Greens. The term "minor party" is also used in a similar manner. Such third political parties rarely win elections, as proportional representation is not used in federal or state elections, but only in some municipal elections.
