Dominant-party system

A dominant-party system, or one-party dominant system, is a system where there is "a category of parties/political organisations that have successively won election victories and whose future defeat cannot be envisaged or is unlikely for the foreseeable future." Many are de facto one-party systems, and often devolve into de jure one-party systems. Usually, the dominant party consistently holds majority government, without the need for coalitions.

Examples commonly cited include: United Russia (CP) in Russia, the Justice and Development Party (AKP) in Turkey, Serbian Progressive Party (SNS) in Serbia, Democratic Party of Socialists of Montenegro (DPS) in Montenegro, the People's Action Party (PAP) in Singapore, the African National Congress (ANC) in South Africa, the Liberal Democratic Party in Japan, Awami League in Bangladesh, MPLA in Angola and the ZANU-PF in Zimbabwe.

Historical overview

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. 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."

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." However, in some countries this is common practice even when there is no dominant party. In contrast to one-party systems, dominant-party systems can occur within a context of a democratic system. In a one-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., the African National Congress 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 current elected government of the District of Columbia has been governed by Democrats since its creation in the 1970s, Bavaria by the Christian Social Union since 1957, and Alberta by Progressive Conservatives 1971-2015. On the other hand, where the dominant party rules nationally on a genuinely democratic basis, the opposition may be strong in one or more subnational areas, possibly even constituting a dominant party locally; an example is South Africa, where although the African National Congress is dominant at the national level, the opposition Democratic Alliance is strong to dominant in the Province of Western Cape.

Canada

Federally, a multi-party system exists, although only two federal parties have ever held power, the Conservative Party and the Liberal Party. However, in some provinces, a party holds hegemonic status over all other parties.

Alberta has voted for the Conservative Party or one of its institutional predecessors (the Progressive Conservative Party, the Reform Party, or the Canadian Alliance) in every single federal election since 1957. The Progressive Conservative Association of Alberta also won every single provincial election from 1971 through 2015. But in surveys now leads the United Conservative Party (UCP) again. The 2015 provincial election saw a surprise win by the New Democratic Party, in part due to the Wildrose Party splitting the conservative vote.

United States

As a whole, the nation has a two-party system, with the main parties since the mid-19th century being Democratic Party and the Republican Party. However, some states and cities have been dominated by one of these parties for up to several decades. The Democratic Party dominate in the urban metropolitan areas, while the Republican Party dominate in the rural areas. Since 2010, majority of the states are dominated by the Republican Party. With control in both the Senate and House of Representatives, and Donald Trump's victory in the 2016 elections, the Republican Party dominate in both federal and state levels.

Dominated by the Democratic Party:

California had a Republican governor as late as 2011 but has voted for Democrats in national races and has a legislature dominated by the Democrats since the 1990s. Due to the top two primary election, many statewide and local races are contested by two members of the Democratic Party in the general election.
- United States presidential election, 2016: Hillary Clinton (Democratic) 61.73% and won 55 electoral votes
- United States Senate election, 2016: Democrats 61.6%
- State Assembly election, 2016: Democrats 61.08% and won 55 of 80 seats

District of Columbia has been continuously ruled by Democrats since the Home Rule Act of 1973 was passed.
Hawaii has been dominated by Democrats since the Democratic Revolution of 1954. Beforehand, the then-Territory of Hawaii was dominated by Republicans and a sugar oligarchy.
New York has an overwhelmingly Democratic population. Democrats have controlled all statewide offices since 2006 (not counting the governor, a Republican was last elected statewide in 2002).
Oregon, while once a heavily Republican state, has had only one Republican governor since 1975, has voted Democrat in every Presidential election since 1988, and had no Republican statewide elected officials from 2002 until the election of Dennis Richardson as Oregon Secretary of State in 2016.
Massachusetts has been dominated by Democrats for several decades, however there have been numbers of Republican governors.
Maryland has been dominated by Democrats since the Civil War, with some exceptions.
Washington, in a manner similar to Oregon, has not had a Republican governor since 1985.

Dominated by the Republican Party:

Alabama: dominated by Republicans since the mid-1990s.
Arizona has been considered a "Republican party stronghold" in recent decades, with a continuous majority in the State House of Representatives since 1967. However, it has elected several Democrats to statewide office and is often considered a swing state in presidential elections.
Idaho has been dominated by Republicans for most of its existence, with no Democratic governors since 1994 and only two years in which the State Senate was tied evenly since 1960.
Illinois is dominated by the Republicans. Chicago, however, has been historically dominated by the Cook County Democratic Party - the office of mayor has been filled by a Democrat continuously since 1931.
Kansas has been dominated by Republicans for most of its existence, with only four years of Democratic majorities in the State House of Representatives since 1915 and only Republican majorities in the same period. Since 1967, however, five of the last nine governors have been Democrats, although one of these Democrats only held office for two years.
Louisiana is dominated by the Republicans. New Orleans, however, has been dominated by the Democratic Party since the 19th century.
Michigan is dominated by the Republicans. Detroit, however, has been dominated by the Democratic Party since the mid-1960s. The city has not had a Republican mayor since the end of Louis Miriani's administration in 1962, and has had just one Republican - Keith Butler - to sit on the Detroit City Council since 1970.
Mississippi: dominated by Republicans since the mid-1990s.
Nebraska has been dominated by Republicans for most of its existence, with a non-partisan (with a de facto Republican majority since records began in 2007) legislature, mostly Republican governors and elected cabinet officials and only one Republican who changed party to Democrat in 2006 holding state-level partisan office since 1999.
South Carolina: dominated by Republicans since the mid-1990s.
South Dakota has been dominated by Republicans for most of its existence, aside from a few Democratic and Populist governments and coalitions with Republicans, with only three elected high officials and two years of State Senate dominance since 1979.
Texas: dominated by Republicans since the mid-1990s.
Utah has been dominated by Republicans for most of its existence, except for Democratic dominance during the Fifth Party System and between 1917 and 1920, the 1890s, and between 1959 and 1984.
Wisconsin is dominated by the Republicans. Milwaukee, however, has been dominated by Democrats since the 1960s. Beforehand, it was dominated by the "Sewer Socialism" movement.
Wyoming has been dominated by Republicans for most of its existence, with only four years where a house of the legislature has been Democratic since 1939, and mostly Republican governors during that period.

Dominant-party systems can also exist on native reservations with republican forms of government. The Seneca Nation of Indians, a tribe with territory within the bounds of New York State, has had the Seneca Party as the dominant party in its political system for several decades.

Former dominant parties

North America

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". The party ruled for most of the 20th century between 1935 and 1984 (the only exceptions being in 1957-1963 and 1979-1980), as well as 1896-1911, 1921-1930 (save a few months), and 1993-2006, with a total of 80 years governed in the past 120 years (As in 2018). After a decade in opposition, the Liberals have returned to power following the 2015 election.
- British Columbia: The Social Credit Party held power for all but 3 years between 1952 and 1991, winning 11 of the 12 elections held during this 39-year period.
- Alberta: The Social Credit Party governed Alberta from 1935 to 1971 and her sister party won all federal elections between 1935 and 1945, except for 1940, and the Alberta PC Party held power from 1971 to 2015.
- Newfoundland and Labrador: The Liberal Party of Newfoundland and Labrador held power from confederation in 1949 until Joey Smallwood's resignation as Premier in 1972, during the hung Parliament created by the Newfoundland general election, 1971.

- Ontario: The Progressive Conservative Party of Ontario, in the Province of Ontario, held office uninterrupted from 1943 to 1985.

Mexico: The Institutional Revolutionary Party (PRI) and its predecessors (Partido Laborista Mexicano (PLM) (1920-1928), Partido Nacional Revolucionario (PNR) (1929-1938) and Partido de la Revolución Mexicana (PRM) (1938-1946)) in Mexico held the presidency from 1920 to 2000. The party governed all states until 1989 and controlled both chambers of congress until 1997. As of 2017, the PRI has continued an uninterrupted hold of the governorship in five states: Coahuila, Colima, Campeche, Hidalgo and the State of Mexico.

United States:
- During the "Era of Good Feelings," the Democratic-Republican Party dominated national politics with no effective opposition from the Federalist Party or any third parties, allowing James Monroe to run unopposed in the 1820 presidential election. This dominance continued until the rise of the American Whig Party circa 1830.
- New England:
  - New Hampshire had mostly Republican governors from 1857-1997 (140 years) - Republicans held the governorship for all but 15 years (were only twice out of office for more than two consecutive years)
  - Vermont had only Republican governors from 1855-1963 (108 years)
- Southern United States:
  - The South (usually defined as coextensive with the former Confederacy) was known until the era of the civil rights movement as the "Solid South" due to its states' reliable support the Democratic Party. Several states had an unbroken succession of Democratic governors for half a century to over a century.
    - Alabama, 1874-1987 (113 years)
    - Arkansas, 1874-1967 (93 years)
    - Florida, 1877-1967 (90 years)

    - Texas, 1874-1979 (105 years)
    - Virginia, 1869-1970 (101 years)
  - During and after that movement, however, factors such as the national Democratic Party's support for the civil rights movement and the national Republican Party's "Southern strategy" since mid-1960s and support for the application of religious values to politics eroded the South's support for the Democrats.

Germany
- Baden-Württemberg: The Christian Democratic Union of Germany ruled from 1953 to 2011 (in Baden and in Württemberg-Hohenzollern ruled the BCSV/CDU 1947-1952 and in Württemberg-Baden 1947-1951) and was biggest party until 2016 (except in Württemberg-Baden for 1950-1952), but is still biggest party at German federal elections and European Parliament elections.

Italy: 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.
Norway: 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.
Portugal: 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 overthrown 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 is still the largest party in Sweden and has been so in every general election since 1917 (hence the largest party even before the universal suffrage was introduces in 1921). The former Prime minister and party leader Tage Erlander led the Swedish government for an uninterrupted tenure of 23 years (1946-1969), the longest in any democracy so far. Since 2006 the party support has declined.
Turkey: 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.
