# Plurality voting

**Plurality voting** is an electoral rule under which the candidate who receives more votes than any other candidate wins the seat, even when that total falls short of an absolute majority of votes cast. In its single-member-district form it is commonly called **first past the post** (FPTP), and it is the voting system used for national elections in the United States, the United Kingdom, Canada, and India, among other countries.<sup>[1](https://legalclarity.org/how-the-first-past-the-post-electoral-system-works/)</sup> Winning under this rule calls for a single vote beyond the closest competitor's total, and the method involves neither a required minimum vote count, a runoff stage, nor any account of the preferences voters may have held for the remaining candidates.<sup>[2](https://legalclarity.org/what-is-the-plurality-method-and-how-does-it-work/)</sup>

## How it works

Each voter picks one candidate from the ballot. Once polls close, officials count each candidate's total, and the person with the highest number wins.<sup>[2](https://legalclarity.org/what-is-the-plurality-method-and-how-does-it-work/)</sup> A majority requires more than 50 percent of the votes cast; plurality requires only more votes than any other single candidate, so the winner needs just one more vote than the nearest rival.<sup>[1](https://legalclarity.org/how-the-first-past-the-post-electoral-system-works/)</sup>

The rule is simple to administer and count. In the United Kingdom, 650 constituencies each hold separate contests, and the candidate with the largest number of votes in each becomes the Member of Parliament.<sup>[7](https://www.gov.uk/elections-in-the-uk/general-election)</sup><sup> • </sup><sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup> Because each contest is decided locally, every MP has a different level of local support, and the winner's share can vary widely between seats.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup>

## Variants within the plurality family

Plurality rule extends beyond the single-member, single-vote form. According to the ACE Electoral Knowledge Network, plurality-majority systems almost always use single-member districts, and when the same rule is applied in multi-member districts it becomes the **Block Vote**, in which voters have as many votes as there are seats to fill and the highest-polling candidates take the positions regardless of the percentage achieved.<sup>[9](https://aceproject.org/main/english/es/esd.htm)</sup> [International IDEA](https://www.edgepedia.org/international-idea)'s glossary adds the **Party Block Vote**, in which voters cast a single party-centered vote and the party with the most votes wins every seat in the district.<sup>[10](https://www.idea.int/data-tools/data/electoral-system-design-database)</sup>

Majoritarian systems sit alongside plurality in the same family but add a majority requirement. The Alternative Vote and the French Two-Round System use voters' second preferences or a second round of voting to produce a winner with an absolute majority, above fifty percent, when no candidate reaches that level in the first round.<sup>[9](https://aceproject.org/main/english/es/esd.htm)</sup>

## Where it is used

First past the post is used in British general elections and in many former British colonies, including the United States, Canada, India, and many Caribbean and African countries. Australia, New Zealand, Ireland, Cyprus, Malta, and South Africa all once used it but have since stopped.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup> Because India has over 800 million voters, most individual voters worldwide cast their ballots under first past the post even though most countries use proportional systems.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup>

The Inter-Parliamentary Union counted 62 national lower chambers using plurality/majority systems as of 31 December 2025, against 76 using proportional representation, 35 mixed systems, and 6 other systems.<sup>[4](https://data.ipu.org/compare/?chart=pie&field=electoral_system&file_format=csv&historical=true&region=&sort=value_asc&structure=any__lower_chamber&year_to=2025)</sup> In the United Kingdom, first past the post applies to the House of Commons, local council elections in [England and Wales](https://www.edgepedia.org/england-and-wales), and Scottish National Park authorities, while devolved and other elections use different systems such as the Additional Member System and the Single Transferable Vote.<sup>[11](https://commonslibrary.parliament.uk/research-briefings/sn04458/)</sup>

## Criticisms and documented effects

**Disproportionality.** Because seats are awarded district by district, a party's seat share can diverge sharply from its vote share. In the 2024 UK general election, Labour won 33.7 percent of the vote and 63.2 percent of MPs; recent [British governments](https://www.edgepedia.org/list-of-british-governments) have been formed on 35 percent of the vote (Labour, 2005) and 37 percent (Conservatives, 2015).<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup> Parties with support spread thinly across the country can win few seats, while geographically concentrated parties can do very well: in 2015 half of Scottish voters voted for the SNP, which took 95 percent of Scotland's seats.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup> The reverse can occur too; in 1951 and 1974 in the UK, and in New Zealand in 1978 and 1981, the party that won the most votes did not win the most seats.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup>

**Spoilers and vote splitting.** Plurality voting is highly vulnerable to spoiler candidates: adding or removing a candidate similar to a front-runner can change the winner, because supporters of minor candidates split the vote.<sup>[5](https://fairvote.org/resources/electoral-systems/comparing-voting-methods/)</sup> In crowded fields the winner's share can be small; in the 2015 Belfast South contest a candidate won with 9,560 votes, or 24.5 percent of the total, a record low.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup> In United States primaries the pattern persists at scale: FairVote counted 125 candidates who won congressional and statewide primary elections in 2026 with a plurality, less than 50 percent, of votes.<sup>[12](https://fairvote.org/report/fewest-votes-wins-plurality-victories-in-2026-primaries/)</sup>

**Strategic voting.** Because a vote for a candidate with little chance of winning risks being wasted, supporters of minor candidates often strategically compromise by voting for a front-runner instead.<sup>[5](https://fairvote.org/resources/electoral-systems/comparing-voting-methods/)</sup> This psychological effect, together with the mechanical effect of denying representation to voters who did not back a winning candidate, underlies Duverger's Law, the proposition that plurality systems tend toward two electoral parties.<sup>[6](https://www.cambridge.org/core/journals/ps-political-science-and-politics/article/why-just-two-parties-a-voting-game-to-illustrate-duvergerslaw/31740530FD6AE83819083E3AF956BFFC)</sup> Comparative research treats the law as a tendency rather than an iron rule, and studies of district-level outcomes across many democracies test how closely it holds in practice.<sup>[13](https://www.cambridge.org/core/journals/british-journal-of-political-science/article/abs/was-duverger-correct-singlemember-district-election-outcomes-in-fiftythree-countries/6FA32DFB3BDF6046F9ED0382029DE29F)</sup>

**Geography and campaigning.** The system creates safe seats, where the outcome is rarely in doubt, and swing seats that parties target with manifestos and campaign spending; voters in safe seats can feel ignored by politicians.<sup>[8](https://www.electoral-reform.org.uk/voting-systems/types-of-voting-system/first-past-the-post/)</sup>

## Alternatives and reform debates

The most common alternatives replace the single plurality count with either preference ranking or a second round. Ranked choice voting (instant runoff voting) lets voters rank candidates and redistributes ballots from eliminated candidates until one has majority support; FairVote's comparison rates it as highly resistant to spoilers, whereas plurality is highly vulnerable.<sup>[5](https://fairvote.org/resources/electoral-systems/comparing-voting-methods/)</sup> Two-round runoffs, used in some US states such as Georgia and Louisiana when no candidate reaches 50 percent, also prevent plurality wins.<sup>[12](https://fairvote.org/report/fewest-votes-wins-plurality-victories-in-2026-primaries/)</sup>

Reform has had mixed political fortunes. The United Kingdom held a 2011 referendum on replacing first past the post with the Alternative Vote for the House of Commons; turnout was 42.2 percent, and the proposal was rejected.<sup>[11](https://commonslibrary.parliament.uk/research-briefings/sn04458/)</sup> In the United States, a roughly $100 million reform campaign placed measures on ballots in seven states in 2024, and nearly all failed; Alaska was the only state where reformers prevailed, rejecting a repeal of its ranked choice system by 737 votes.<sup>[14](https://www.theatlantic.com/politics/archive/2024/12/election-reform-ranked-choice-partisan-primaries/680912/)</sup> Research summarized by the [American Bar Association](https://www.edgepedia.org/american-bar-association) finds evidence that ranked choice voting improves on plurality voting in representation, campaign quality, mobilization, and turnout.<sup>[15](https://www.americanbar.org/groups/public_interest/election_law/american-democracy/our-work/what-we-know-about-ranked-choice-voting-2025/)</sup>
