Two-party System - Third Parties

Third Parties

Third parties, meaning a party other than one of the two dominant parties, are possible in two-party systems, but they are 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 parties in a two-party system can be:

• built around a particular ideology or interest group
• split off from one of the major parties or
• focused on a charismatic individual.

When third parties are built around an ideology which is at odds with the majority mindset, many members belong to such a party not for the purpose of expecting electoral success but rather for personal or psychological reasons. In the U.S., third parties include older ones such as the Libertarian Party and the Green Party and newer ones such as the Pirate Party. Many believe that third parties don't affect American politics by winning elections, but they can act as "spoilers" by taking votes from one of the two major parties. They act like barometers of change in the political mood since they push the major parties to consider their demands. An analysis in New York Magazine by Ryan Lizza in 2006 suggested that third parties arose from time to time in the nineteenth century around single-issue movements such as abolition, women's suffrage, and the direct election of senators, but were less prominent in the twentieth century.

A so-called third party in the United Kingdom are the Liberal Democrats. In the 2010 election, the Liberal Democrats received 23% of the votes but only 9% of the seats in the House of Commons. While electoral results do not necessarily translate into legislative seats, the Liberal Democrats can exert influence if there is a situation such as a hung parliament. In this instance, neither of the two main parties (at present, the Conservative Party and the Labour Party) have sufficient authority to run the government. Accordingly, the Liberal Democrats can in theory exert tremendous influence in such a situation since they can ally with one of the two main parties to form a coalition. This happened in the Coalition government of 2010. Yet in that more than 13% of the seats in the British House of Commons are held in 2011 by representatives of political parties other than the two leading political parties of that nation, contemporary Britain is considered by some to be a multi-party system, and not a two-party system.
