Two-party system

The 1932 United States elections saw the onset of the Fifth Party System and a long period of Democratic dominance due to the New Deal Coalition.

Modern American politics, in particular the electoral college system, has been described as duopolistic since the Republican and Democratic parties have dominated and framed policy debate as well as the public discourse on matters of national concern for about a century and a half.

Third Parties have encountered various blocks in getting onto ballots at different levels of government as well as other electoral obstacles, such as denial of access to general election debates.

The Republic of Ghana since its transition to democracy in 1992 have a strongly institutionalized two-party system led by New Patriotic Party and National Democratic Congress.

Due to the common accumulation of power in the presidential office both the official party and the main opposition became important political protagonists causing historically two-party systems.

[22] Some of the first manifestations of this particularity was with the liberals and conservatives that often fought for power in all Latin America causing the first two-party systems in most Latin American countries which often lead to civil wars in places like Colombia, Ecuador, Mexico, Venezuela, the Central American Republic and Peru, with fights focusing specially on opposing/defending the privileges of the Catholic Church and the creole aristocracy.

There has been speculation that a two-party system arose in the United States from early political battling between the federalists and anti-federalists in the first few decades after the ratification of the Constitution, according to several views.

[1] Political scientists such as Maurice Duverger[32] and William H. Riker claim that there are strong correlations between voting rules and type of party system.

Members of Congress are elected in single-member districts according to the "first-past-the-post" (FPTP) principle, meaning that the candidate with the plurality of votes is the winner of the congressional seat.

What happens is that in a general election, a party that consistently comes in third in every district is unlikely to win any legislative seats even if there is a significant proportion of the electorate favoring its positions.

Politically oriented people consider their only realistic way to capture political power is to run under the auspices of the two dominant parties,[1] and legislators from both dominant parties have an incentive not to reform the system as it eliminates potential choices and multiple competing policy options, meaning that they do not necessarily need to adopt positions favorable to voters, but only need to be seen as marginally less unfavorable than the only other option to gain votes.

[1] Duverger concluded that "plurality election single-ballot procedures are likely to produce two-party systems, whereas proportional representation and runoff designs encourage multipartyism.

[1] 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.

[37] 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.

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.

Some historians have suggested that two-party systems promote centrism and encourage political parties to find common positions which appeal to wide swaths of the electorate.

Historian Patrick Allitt of the Teaching Company suggested that it is difficult to overestimate the long-term economic benefits of political stability.

[43] Italy, with a multi-party system, has had years of divisive politics since 2000, although analyst Silvia Aloisi suggested in 2008 that the nation may be moving closer to a two-party arrangement,[44] although this no longer seemed the case by the 2010s, which saw the rise of the Five Star Movement and Lega.

If there is any truth to Schattschneider's analogy between elections and markets, America's faith in the two–party system begs the following question: Why do voters accept as the ultimate in political freedom a binary option they would surely protest as consumers?

This is the tyranny of the two–party system, the construct that persuades United States citizens to accept two–party contests as a condition of electoral democracy.There have been arguments that the winner-take-all mechanism discourages independent or third-party candidates from running for office or promulgating their views.

[49] He makes a case that the American president should be elected on a non-partisan basis,[49][50][51] and asserts that both political parties are "cut from the same cloth of corruption and corporate influence.

Whether it's dealing with ISIS, the debt ceiling, or climate change, the media frames every issue as a simple debate between the Democratic and the Republican positions.

[55] In the following century, the Whig party's support base widened to include emerging industrial interests and wealthy merchants.

The basic matters of principle that defined the struggle between the two factions, were concerning the nature of constitutional monarchy, the desirability of a Catholic king, the extension of religious toleration to nonconformist Protestants, and other issues that had been put on the liberal agenda through the political concepts propounded by John Locke,[56] Algernon Sidney and others.

[57] Vigorous struggle between the two factions characterised the period from the Glorious Revolution to the 1715 Hanoverian succession, over the legacy of the overthrow of the Stuart dynasty and the nature of the new constitutional state.

This proto two-party system fell into relative abeyance after the accession to the throne of George I and the consequent period of Whig supremacy under Robert Walpole, during which the Tories were systematically purged from high positions in government.

Although the Tories were dismissed from office for 50 years, they retained a measure of party cohesion under William Wyndham and acted as a united, though unavailing, opposition to Whig corruption and scandals.

Burke laid out a philosophy that described the basic framework of the political party as "a body of men united for promoting by their joint endeavours the national interest, upon some particular principle in which they are all agreed".

[59] A genuine two-party system began to emerge,[60] with the accession to power of William Pitt the Younger in 1783 leading the new Tories, against a reconstituted "Whig" party led by the radical politician Charles James Fox.

The modern Conservative Party was created out of the "Pittite" Tories by Robert Peel, who issued the Tamworth Manifesto in 1834 which set out the basic principles of Conservatism – the necessity in specific cases of reform in order to survive, but an opposition to unnecessary change, that could lead to "a perpetual vortex of agitation".

Voting ballot.
In a two-party system, voters have mostly two options; in this sample ballot for an election in Summit, New Jersey , voters can choose between a Republican or Democrat, but there are no third party candidates.
According to one view, the winner-takes-all system discourages voters from choosing third party or independent candidates, and over time the process becomes entrenched so that only two major parties become viable.
