Dominant-party system

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A dominant-party system or one-party dominant system, is a system where there is "a category of parties/political organizations that have successively won election victories and whose future defeat cannot be envisaged or is unlikely for the foreseeable future."[1] A wide range of parties have been cited as being dominant at one time or another, including the Kuomintang in the Republic of China, the African National Congress (ANC) in South Africa and the Liberal Democratic Party in Japan.[1] Such dominance has not always been a matter of concern, with, for example, the dominance of the Indian National Congress being seen by some as source of stability supportive of the consolidation of democracy.[1]

Opponents of the "dominant party" system or theory argue that it views the meaning of democracy as given, and that it assumes that only a particular conception of representative democracy (in which different parties alternate frequently in power) is valid.[1] One author argues that "the dominant party 'system' is deeply flawed as a mode of analysis and lacks explanatory capacity. But it is also a very conservative approach to politics. Its fundamental political assumptions are restricted to one form of democracy, electoral politics and hostile to popular politics. This is manifest in the obsession with the quality of electoral opposition and its sidelining or ignoring of popular political activity organised in other ways. The assumption in this approach is that other forms of organisation and opposition are of limited importance or a separate matter from the consolidation of their version of democracy."[1]

One of the dangers of dominant parties is "the tendency of dominant parties to conflate party and state and to appoint party officials to senior positions irrespective of their having the required qualities."[1] However, in some countries this is common practice even when there is no dominant party.[1] In contrast to single-party systems, dominant-party systems can occur within a context of a democratic system. In a single-party system other parties are banned, but in dominant-party systems other political parties are tolerated, and (in democratic dominant-party systems) operate without overt legal impediment, but do not have a realistic chance of winning; the dominant party genuinely wins the votes of the vast majority of voters every time (or, in authoritarian systems, claims to). Under authoritarian dominant-party systems, which may be referred to as "electoralism" or "soft authoritarianism", opposition parties are legally allowed to operate, but are too weak or ineffective to seriously challenge power, perhaps through various forms of corruption, constitutional quirks that intentionally undermine the ability for an effective opposition to thrive, institutional and/or organizational conventions that support the status quo, or inherent cultural values averse to change.

In some states opposition parties are subject to varying degrees of official harassment and most often deal with restrictions on free speech (such as press club), lawsuits against the opposition, rules or electoral systems (such as gerrymandering of electoral districts) designed to put them at a disadvantage. In some cases outright electoral fraud keeps the opposition from power. On the other hand, some dominant-party systems occur, at least temporarily, in countries that are widely seen, both by their citizens and outside observers, to be textbook examples of democracy. The reasons why a dominant-party system may form in such a country are often debated: Supporters of the dominant party tend to argue that their party is simply doing a good job in government and the opposition continuously proposes unrealistic or unpopular changes, while supporters of the opposition tend to argue that the electoral system disfavors them (for example because it is based on the principle of first past the post), or that the dominant party receives a disproportionate amount of funding from various sources and is therefore able to mount more persuasive campaigns. In states with ethnic issues, one party may be seen as being the party for an ethnicity or race with the party for the majority ethnic, racial or religious group dominating, e.g., ANC in South Africa (governing since 1994) has strong support amongst Black South Africans, the Ulster Unionist Party governed Northern Ireland from its creation in 1921 until 1972 with the support of the Protestant majority.

Sub-national entities are often dominated by one party due the area's demographic being on one end of the spectrum. For example the District of Columbia has been governed by Democrats since its creation, Bavaria by the Christian Social Union since 1957, Alberta by Progressive Conservatives since 1971. In contrast some sub-national entities have comparatively more conservative or liberal forms of the parties in their entity, for example an Oklahoma Democrat is likely to be at least as conservative as a Minnesota Republican.

Former dominant parties[edit]

North America[edit]

  •  Canada: The Liberal Party of Canada was the dominant party in the federal government of Canada for so much of its history that it is sometimes given the moniker "Canada's natural governing party".[9] The party experienced several long uninterrupted periods in power including 1873-1878, 1896-1911, 1921-1926, 1926-1930, 1935-1957, 1963-1979, 1980-1984, and 1993-2006.
  • The South (usually defined as coextensive with the former Confederacy, with the exception of western and sometimes central Texas) was known until the era of the civil-rights movement as the "Solid South" due to its states' reliable support of the United States' Democratic Party. Several states had an unbroken succession of Democratic governors for several decades or over a century.

  • In Turkey's single-party period, the Republican People's Party became the major political organisation of a single-party state. However, CHP faced two opposition parties during this period, both established upon the request of the founder of Turkey and CHP leader, Mustafa Kemal Atatürk, in efforts to jump-start multiparty democracy in Turkey.[10]
  • Italy's Christian Democracy dominated the Italian politics for almost 50 years as the major party in every coalition that governed the country from 1944 until its demise amid a welter of corruption allegations in 1992–1994. The main opposition to the Christian democratic governments was the Italian Communist Party.
  • The Portuguese Republican Party, during most of the Portuguese First Republic's existence (1910–1926): After the coup that put an end to Portugal's constitutional monarchy in 1910, the electoral system, which had always ensured victory to the party in government, was left unchanged. Before 1910, it had been the reigning monarch's responsibility to ensure that no one party remain too long in government, usually by disbanding Parliament and calling for new elections. The republic's constitution added no such proviso, and the Portuguese Republican Party was able to keep the other minor republican parties (monarchic parties had been declared illegal) from winning elections. On the rare occasions when it was ousted from power, it was overtrown by force and was again by the means of a counter-coup that it returned to power, until its final fall, with the republic itself, in 1926.
  • The Party of the Right in Luxembourg (1917–1925)
  • The Ulster Unionist Party in the former devolved administration of Northern Ireland between 1921 to 1972.[11]

  • The Norwegian Labour Party ruling from 1935 to 1965, though it has been the biggest party in Norway since 1927 and has been in power many other times.
  • The Scottish Labour Party won every election in Scotland between the 1960s and the present day and controlled the Scottish Parliament until the 2007 election.
