A winner-take-all (or winner-takes-all) electoral system is one where a voting bloc can win all seats in a legislature or electoral district, denying representation to any political minorities. Such systems are used in many major democracies. Such systems are sometimes called "majoritarian representation", though this term is a misnomer, as most such systems do not always elect majority preferred candidates and do not always produce winners who received majority of votes cast in the district, and they allow parties to take a majority of seats in the chamber with just a minority of the vote.
Any election with only a single seat is a winner-take-all system (as it is impossible for the winner to take less than one seat). As a result, legislatures elected by single-member districts are often described as using "winner-take-all". However, winner-take-all systems do not necessarily mean the majority of voters are represented properly. A minority of voters across the country may take all the seats; a minority of votes cast in a district may elect all the winners in a district. Conversely, a party with just a sliver of votes in a country-wide sense may have local dominance and take a seat in a particular constituency, or such an extreme candidate can win even with just a plurality in the district, leaving the majority in the district unrepresented.
Formally, a voting system is called winner-take-all if a majority of voters, by coordinating, can force all seats up for election in their district, denying representation to all minorities. By definition, all single-winner voting systems are winner-take-all. For multi-winner elections, the electorate can be divided into constituencies, such as single-member districts (SMDs), or the election can be held using block voting with at-large or multi-member districts.
Majoritarian representation does not mean the party with a plurality or majority always receive a majority of seats, which is not always guaranteed (see hung parliament). Sometimes the party receiving the most votes gets fewer seats than the party with the second most votes (see electoral inversion).

Electoral system | Party | Seat distribution | Explanation of example | |||
A | B | C | D | |||
Block voting | 100 | 0 | 0 | 0 | If the whole assembly is elected in a single (nationwide) constituency under party block voting using block FPP, the party with the highest number of votes always can win all the seats, as long as it does not run too many candidates who split the vote. | |
Single-member district | 64 | 33 | 0 | 3 | If the assembly is elected in single-member districts using the first-past-the-post (single-member plurality) method, the candidate with the highest number of votes wins (the only) seat in their district. Often, the party with the highest number of votes wins in a landslide as shown here, but electoral inversion is still possible, as well as the case where no party receives an outright majority of seats (called a hung parliament in the UK). |
The principle of majoritarian democracy does not necessarily imply that a winner-take-all electoral system needs to be used, in fact, using proportional systems to elect legislature usually better serve this principle as such aims to ensures that the legislature accurately reflects the whole population, not just the winners of the election and the majority rule is then used within the legislature. The most widely accepted modern views of representative democracy no longer consider winner-take-all representation to be democratic. For this reason, nowadays winner-take-all representation is most often used in single-winner districts, which allows nationwide minorities to gain representation if they make up a plurality or majority in at least one district, but some also consider this anti-democratic because of the possibility of an electoral inversion (like in the case of some US presidential elections: 2000, 2016).
Winner-take-all and proportional systems are the most commonly used voting system worldwide, followed by mixed electoral systems, which usually combine winner-take-all and proportional representation, although there are mixed system that combine two winner-take-all systems as well. Winner-take-all representation is also contrasted with proportional representation, which provides for representation of political minorities according to their share of the popular vote and semi-proportional representation, which inherently provides for some representation of minorities (at least above a certain threshold). Within mixed systems, mixed-member majoritarian representation (also known as parallel voting) provides semi-proportional representation, as opposed to mixed-member proportional systems.
Historically the first multi-winner electoral systems were winner-take-all elections held at-large, or more generally the multiple non-transferable vote.[ citation needed ]
Until the first half of the 19th century, the classic winner-take-all system of block voting began to be more and more criticized. This introduced in two senses:
The version of block voting using electoral lists instead of individual candidates (general ticket or party block voting) was almost completely replaced by party-list proportional voting systems, which fully abandon the winner-take-all ideal in favor of equal representation. However, with the majority bonus or majority jackpot types of mixed system, this type of winner-take-most system has partially reappeared in certain electoral systems.
Winner-take-all representation using single-winner districts is the most common form of pure winner-take-all systems today, with the most common being single-member plurality (SMP).
However, due to high disproportionalities, it is also considered undemocratic by many.[ who? ] In Europe only Belarus and the United Kingdom use FPTP/SMP to elect the primary (lower) chamber of their legislature and France uses a two-round system (TRS). All other European countries either use proportional representation or use winner-take-all representation as part of a mixed-member winner-take-all system (Andorra, Italy, Hungary, Lithuania, Russia and Ukraine) or a mixed-member proportional system (Germany). However, other European countries also occasionally use winner-take-all systems (apart from single-winner elections, like presidential or mayoral elections) for elections to the secondary chamber (upper house) of their legislature (Poland) and sub-national (local and regional) elections.
Winner-take-all system are much more common outside Europe, particularly in the countries of the former British Empire, like Australia (IRV), Bangladesh, Canada, Egypt, India, Pakistan and the United States (FPTP/SMP).
Nowadays, at-large winner-take-all representation is used for national elections only in the Senate of the Philippines, while it is sometimes still used for local elections organised on non-partisan bases. Residual usage in several multi-member constituencies is reduced to the election of the Electoral college of the President of the United States. Block voting is also used to elect a part of the assemblies in the regional elections in Italy and France.

Plurality voting refers to electoral systems in which the candidates in an electoral district who poll more than any other are elected.
Proportional representation (PR) refers to any type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions among voters. The essence of such systems is that all votes cast – or almost all votes cast – contribute to the result and are effectively used to help elect someone. Under other election systems, a bare plurality or a scant majority are all that are used to elect candidates. PR systems provide balanced representation to different factions, reflecting how votes are cast.
Single non-transferable vote or SNTV is an electoral system used to elect multiple winners. It is a semi-proportional variant of first-past-the-post voting, applied to multi-member districts where each voter casts just one vote. It can also be seen as a variant of STV but with no vote transfers.
The additional-member system (AMS) is a two-vote seat-linkage-based mixed electoral system used in the United Kingdom in which most representatives are elected in single-member districts (SMDs), and a fixed number of other "additional members" are elected from a closed list to make the seat distribution in the chamber more proportional to the votes cast for party lists. It is distinct from using parallel voting for the list seats in that the "additional member" seats are awarded to parties taking into account seats won in SMDs – these are ignored under parallel voting.
Mixed-member proportional representation is a type of representation provided by some mixed electoral systems which combine local winner-take-all elections with a compensatory tier with party lists, in a way that produces proportional representation overall. Like proportional representation, MMP is not a single system, but a principle and goal of several similar systems. Some systems designed to achieve proportionality are still called mixed-member proportional, even if they generally fall short of full proportionality. In this case, they provide semi-proportional representation.
Block or bloc voting refers to a class of electoral systems where multiple candidates are elected simultaneously. They do not guarantee minority representation and allow a group of voters to ensure that only their preferred candidates are elected. In these systems, a voter can select as many candidates as there are open seats. That is, the voter has as many votes to cast as the number of seats to fill. The block voting systems are among various election systems available for use in multi-member districts where the voting system allows for the selection of multiple winners at once.
First-past-the-post voting (FPTP), also known as first-preference plurality (FPP) or single-member district plurality (SMDP)—often shortened simply to plurality—is a single-winner voting rule. Voters typically mark one candidate as their favorite, and the candidate with the largest number of first-preference marks is elected, regardless of whether they have over half of all votes. The name first-past-the-post is a reference to gambling on horse races. In social choice, FPP is generally treated as a degenerate variant of ranked voting, where voters rank the candidates, but only the first preference matters. As a result, FPP is usually implemented with a choose-one ballot, where voters place a single bubble next to their favorite candidate.
In political science, parallel voting or superposition refers to the use of two or more electoral systems to elect different members of a legislature. More precisely, an electoral system is a superposition if it is a mixture of at least two tiers, which do not interact with each other in any way; one part of a legislature is elected using one method, while another part is elected using a different method, with all voters participating in both. Thus, the final results can be found by calculating the results for each system separately based on the votes alone, then adding them together. A system is called fusion or majority bonus, another independent mixture of two system but without two tiers. Superposition is also not the same as "coexistence", which when different districts in the same election use different systems. Superposition, fusion and coexistence are distinct from dependent mixed electoral systems like compensatory (corrective) and conditional systems.
An electoraldistrict, sometimes called a constituency, riding, or ward, is a subdivision of a larger state created to provide its population with representation in the larger state's legislature. That body, or the state's constitution or a body established for that purpose, determines each district's boundaries and whether each will be represented by a single member or multiple members. Generally, only voters (constituents) who reside within the district are permitted to vote in an election held there. District representatives may be elected by a first-past-the-post system, a proportional representative system, or another voting method. They may be selected by a direct election under universal suffrage, an indirect election, or another form of suffrage.
A plurality or majority bonus system (MBS) (also called minority friendly majoritarian electoral system) is a mixed-member, partly-proportional electoral system that gives extra seats in a legislature to the party with a plurality or majority of seats. Typically, this is done with the aim of providing government stability, particularly in parliamentary systems.
A party-list system is a type of electoral system that formally involves political parties in the electoral process, usually to facilitate multi-winner elections. In party-list systems, parties put forward a list of candidates, the party-list who stand for election on one ticket. Voters can usually vote directly for the party-list, but in other systems voters may vote directly for individual candidates within or across party lists, instead of voting directly for parties.
Plurality block voting is a type of block voting method for multi-winner elections. Each voter may cast as many votes as the number of seats to be filled. The candidates with the most votes are elected. The usual result when the candidates divide into parties is that the most-popular party in the district sees its full slate of candidates elected, even if the party does not have support of majority of the voters.
Semi-proportional representation characterizes multi-winner electoral systems which allow representation of minorities, but are not intended to reflect the strength of the competing political forces in close proportion to the votes they receive. Semi-proportional voting systems are generally used as a compromise between complex and expensive but more-proportional systems and simple winner-take-all systems. Examples of semi-proportional systems include the single non-transferable vote, limited voting, and parallel voting.
An electoral or voting system is a set of rules used to determine the results of an election. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign spending, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices.
A mixed electoral system is one that uses different electoral systems to elect different seats in a legislature. Most often, this involves a winner-take-all component combined with a proportional component. The results of the combination may be mixed-member proportional (MMP), where the overall results of the elections are proportional, or mixed-member majoritarian, in which case the overall results are semi-proportional, retaining disproportionalities from the majoritarian component. Systems that use multiple types of combinations are sometimes called supermixed.
A mixed single vote (MSV) is a type of ballot in mixed-member electoral systems, where voters cast a single vote in an election, which used both for electing a local candidate and as a vote for a party affiliated with that candidate according to the rules of the electoral system. Unlike most mixed proportional and mixed majoritarian systems where voters cast two votes, split-ticket voting is not possible under MSV. This significantly reduces the possibility of manipulating compensatory mixed systems, at the price of reducing voter choice. An alternative based on the mixed single vote that still allows for indicating different preferences on different levels is the mixed ballot, which functions as a preferential (mixed) single vote.
Mixed-member majoritarian representation (MMM) is type of a mixed electoral system combining winner-take-all and proportional methods, where the disproportional results of the winner-take-all part are dominant over the proportional component. Mixed member majoritarian systems are therefore categorized under semi-proportional representation, and are usually contrasted with mixed-member proportional representation (MMP) which aims to provide proportional representation compensation ("top-up") seats.
Compensation or correction is an optional mechanism of electoral systems, which corrects the results of one part of the system based on some criterion to achieve a certain result, usually to make it more proportional. There are in general two forms of compensation: vote linkage and seat linkage.
The vote linkage or (multi-tier) vote transfer system is type of compensatory mixed electoral system, where votes may be transferred across multiple tiers of an electoral system, in order to avoid wasted votes - in contrast to the more common seat linkage compensatory system. It often presupposes and is related to the concept of the mixed single vote, which means that the same vote can be used in multiple tiers of an electoral system and that a vote for a local candidate may automatically count as a vote for the candidate's party or the other way around. Voters usually cast their single vote for a local candidate in a single-member district (SMD) and then all the wasted votes from this lower tier are added to distribute seats between upper tier candidates, typically national party lists.
