Two-party system
A two-party system is a political party system in which two major political parties[1] consistently dominate the political landscape. At any point in time, one of the two parties typically holds a majority in the legislature and is usually referred to as the majority or governing party while the other is the minority or opposition party. Around the world, the term has different meanings. For example, in the United States, the Bahamas, Jamaica, and Zimbabwe, the sense of two-party system describes an arrangement in which all or nearly all elected officials belong to either of the two major parties, and third parties rarely win any seats in the legislature. In such arrangements, two-party systems are thought to result from several factors, like Duverger's law, sometimes referred to as "winner-takes-all",[2] [3] [4][5], first past the post[6], and deep-state entrenchment.[citation needed]
In such systems, while chances for third-party candidates winning election to major national office are remote, it is possible for groups within the larger parties ("political factions"), or in opposition to one or both of them, to exert influence on the two major parties.[7][8][9][10][11][12] In contrast, in Canada, the United Kingdom and Australia and in other parliamentary systems and elsewhere, the term two-party system is sometimes used to indicate an arrangement in which two major parties dominate elections but in which there are viable third parties or independents that do win some seats in the legislature, and in which the two major parties exert proportionately greater influence than their percentage of votes would suggest.
Explanations for why a political system with free elections may evolve into a two-party system have been debated. A leading theory, referred to as Duverger's law, states that two parties are a natural result of a winner-take-all voting system.
Generally, a two-party system becomes a dichotomous division of the political spectrum with an ostensibly left-wing and right-wing party: the Democratic Party versus the Republican Party in the United States, the Australian Labor Party versus the Liberal–National Coalition bloc in Australia, the Labour Party versus the Conservative Party in the United Kingdom, and the Malta Labour Party versus the Malta Nationalist Party in Malta.
Other parties in these countries may have seen candidates elected to local or subnational office.[13]
