Multiple non-transferable vote

Last updated

The multiple non-transferable vote (MNTV) is a group of voting system, in which voters elect several representatives at once, with each voter having more than one vote. MNTV uses multi-member electoral districts or only one district, which contains all voters, which is used to provide at-large representation.

Contents

MNTV systems are not designed towards obtaining proportional representation; instead the usual result is that where the candidates divide into definitive parties (especially for example where those parties have party lines which are whipped) the most popular party in the district sees its full slate of candidates elected, resulting in a landslide.

The exceptions to this are Limited Voting or Cumulative Voting, both of which are brought in on purpose to produce diverse representation—minority representation as well as representation of the largest group. But other systems have proven themselves more dependable at producing Proportional Representation than those two - party-list PR or Single Transferable Voting, for example.

MNTV systems include:

The multiple winners are usually elected simultaneously in one round of voting and the vote is non-transferable, unlike under preferential block voting. MNTV sometimes appears in a runoff (two-round) version, as in some local elections in France, where candidates who do not receive an absolute majority must compete in a second round. In these cases, it is more accurately called "majority-at-large voting".

The single non-transferable vote (SNTV) is the extreme version of limited voting, when each voter can vote for only one candidate.

Terminology

Block voting

The term "plurality at-large" is in common usage in elections for representative members of a body who are elected or appointed to represent the whole membership of the body (for example, a city, state or province, nation, club or association). Where the system is used in a territory divided into multi-member electoral districts the system is commonly referred to as "block voting" or the "bloc vote". Block voting as described in this article is "unlimited voting", unlike "limited voting", where a voter has fewer votes than the number of seats contested. The term "block voting" sometimes means simple plurality election of slates (electoral lists) in multi-member districts. In such a system, each party puts forward a slate (party-list) of candidates, a voter casts just one vote, and the party winning a plurality of votes sees its whole slate elected, winning all the seats.

Variations of the MNTV

Plurality block voting (BV)

In a block voting election, all candidates run against each other for m number of positions, where m is commonly called the district magnitude. Each voter selects up to m candidates on the ballot (voters are sometimes said to have m votes; however, they are unable to vote for the same candidate more than once as is permitted in cumulative voting [2] ). Voters are most commonly permitted to cast their votes across more than one party list. [3] The m candidates with the most votes (who may or may not obtain a majority of available votes) are the winners and will fill the positions.

Majority-at-large voting / Two-round block voting

The majority-at-large voting is the plurality-at-large voting, but candidates who do not receive an absolute majority must compete in a second round.

Limited voting (LV) / Partial block voting

Partial block voting, also called limited voting, functions similarly to plurality-at-large voting, however in partial block voting each voter receives fewer votes than the number of candidates to be elected. This in turn can enable reasonably sized minorities to achieve some representation, as it becomes impossible for a simple plurality to sweep every seat. Partial bloc voting is used for elections to the Gibraltar Parliament, where each voter has 10 votes and 17 seats are open for election; the usual result is that the most popular party wins 10 seats and forms the ruling administration, while the second most popular wins seven seats and forms the opposition. Partial block voting is also used in the Spanish Senate, where there are four seats per constituency and each voter receives three votes. Historically, partial block voting was used in three- and four-member constituencies in the United Kingdom, where voters received two votes, until multimember constituencies were abolished.

Under partial block voting, the fewer votes each voter is granted the smaller the number of voters needed to win becomes and the more like proportional representation the results can be, provided that voters and candidates use proper strategy. [4] At the extreme, if each voter receives only one vote, then the voting system becomes equivalent to the single non-transferable vote. Many votes can be wasted and vote-splitting can produce unfair results (but likely more balanced than elections under Block Voting). Due to these reasons, the portion of votes needed to win a seat under SNTV may be quite small indeed. (Single transferable voting is more scientific, producing less wasted votes. Under STV, the minimum proportion needed to assure victory is the Droop quota, although commonly one or two in each contest are elected with less than that.)

Block approval voting

In block approval voting, every voter may vote for any number of candidates (but no more than once for each candidate)

Cumulative voting

General ticket / Party block voting (PBV)

Party block voting (PBV), or general ticket, is the party-list version of the block vote. In contrast to the classic block vote, where the candidates may formally stand as non-partisan and some minority nominations can be theoretically successful, PBV each candidate are linked to their party-list, which is voted by the electors producing a landslide, and any minority representation is excluded. This system is used to elect the vast majority of the Parliament of Singapore.

Compared to preferential block voting

Block voting, or plurality block voting, is often compared with preferential block voting as both systems tend to produce landslide victories for similar candidates. Instead of a series of checkboxes, preferential block voting uses a preferential ballot, therefore it is not a multiple non-transferable vote, but a multiple transferable vote. A slate of clones of the top preferred candidate will win every seat under both systems, however in preferential block voting this is instead the instant-runoff winner.

Plurality voting refers to electoral systems in the candidates in an electoral district who poll more than any other are elected. Used for elections of various offices or representative bodies, it is often contrasted with proportional representation. Plurality voting is also called simple majority or relative majority voting, however, is it also often explicitly distinguished from majority voting, in which a winning candidate must receive an absolute majority of votes: more than half of all votes.

<span class="mw-page-title-main">Proportional representation</span> Voting system that makes outcomes proportional to vote totals

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 – not just a bare plurality or (exclusively) the majority – and that the system produces mixed, balanced representation reflecting how votes are cast.

<span class="mw-page-title-main">Two-round system</span> Voting system

The two-round system (TRS), also known as runoff voting, second ballot, or ballotage, is a voting method used to elect a single candidate. The first round is held using simple plurality to choose the top-two candidates, and then in the second round the winner is chosen by majority vote. The two-round system is widely used in the election of legislative bodies and directly elected presidents.

<span class="mw-page-title-main">Single transferable vote</span> Multi-winner electoral system

The single transferable vote (STV) is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked-choice ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternate preferences if their preferred candidate is eliminated or elected with surplus votes, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another.

Single non-transferable vote or SNTV is an electoral system used to elect multiple winners. It is a generalization of first-past-the-post, applied to multi-member districts with each voter casting just one vote. Unlike FPTP, which is a single-winner system, in SNTV multiple winners are elected, typically in electoral districts; additionally, unlike FPTP, SNTV produces mixed representation and makes it unlikely for a single party to take all the seats in a city or a set area, which can happen under FPTP.

Cumulative voting is a multiple-winner method intended to promote more proportional representation than winner-take-all elections such as block voting or first past the post. Cumulative voting is used frequently in corporate governance, where it is mandated by some (7) U.S. states.

Block voting, also known as bloc voting, refers to certain 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.

<span class="mw-page-title-main">First-past-the-post voting</span> Electoral system where voters vote for one candidate and the candidate with the most votes wins

First-past-the-post voting is a plurality voting system wherein voters cast a vote for a single candidate, and the candidate with the most votes wins the election. Analogous systems for multi-winner contests are known as plurality block voting or "block voting" systems; both FPTP and block voting are "plurality" systems in that the winner needs only a plurality of the votes and not an absolute majority. The term first-past-the-post is a metaphor from horse racing of the plurality-voted candidate winning such a race; the electoral system is formally called single-member [district] plurality voting (SMP/SMDP) when used in single-member districts, and informally called choose-one voting in contrast to ranked voting or score voting.

Parallel voting is a type of mixed electoral system in which representatives are voted into a single chamber using two or more different systems, most often first-past-the-post voting (FPTP) with party-list proportional representation (PR). It is the most common form of mixed member majoritarian representation (MMM), which is why these terms are often used synonymously with each other. In some countries, parallel voting is known as the supplementary member (SM) system, while in academic literature it is sometimes called the superposition method within mixed systems.

An electoral district, also known as an election district, legislative district, voting district, constituency, riding, ward, division, electorate, or (election) precinct, is a subdivision of a larger state created to provide its population with representation in the larger state's constituency. 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.

Limited voting is a voting system in which electors have fewer votes than there are positions available. The positions are awarded to the candidates who receive the most votes. In the special case in which the voter may vote for only one candidate and there are two or more posts, this system is called the single non-transferable vote or sometimes the strictly limited vote.

The general ticket, also known as party block voting (PBV) or ticket voting, is a type of block voting in which voters opt for a party, or a team's set list of candidates, and the highest-polling party/team becomes the winner. Unless specifically altered, this electoral system results in the victorious political party receiving 100% of the seats. Rarely used today, the general ticket is usually applied in more than one multi-member district, which theoretically allows regionally strong minority parties to win some seats, but the strongest party nationally still typically wins with a landslide.

Preferential block voting is a majoritarian voting system for electing several representatives from a multimember constituency, such as a state. Unlike single transferable voting (STV) or list PR, preferential block voting is not a method for obtaining proportional representation, and instead produces similar results to plurality block voting. Preferential block voting can be seen as a multiple-winner version of instant-runoff, a multiple transferable vote (MTV).

Plurality block voting, also known as plurality-at-large voting, bloc vote or block voting (BV) is a non-proportional voting system for electing representatives in multi-winner elections. Each voter may cast as many votes as the number of seats to be filled. 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 in a seemingly landslide victory.

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 can be regarded as compromises between forms of proportional representation such as party-list PR, and plurality/majoritarian systems such as first-past-the-post voting. Examples of semi-proportional systems include the single non-transferable vote, limited voting, and parallel voting.

<span class="mw-page-title-main">Electoral system</span> Method by which voters make a choice between options

An electoral system or voting system is a set of rules that determine how elections and referendums are conducted and how their results are determined. 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 majoritarian electoral system is an electoral system where the candidates or parties with the most votes takes all seats using the winner-takes-all principle and in this way provides majoritarian representation. However, there are many electoral systems considered majoritarian based on different definitions, including types of at-large majoritarian representation such as block voting or party block voting, but district-based majoritarian systems such as first-past-the-post voting (FPTP/SMP). Where two candidates are in the running, the one with the most votes will have a majority, but where there are three or more candidates, it often happens that no candidate takes a majority of the votes.

Dual-member proportional representation (DMP), also known as dual-member mixed proportional, is an electoral system designed to produce proportional election results across a region by electing two representatives in each of the region’s districts. The first seat in every district is awarded to the candidate who receives the most votes, similar to first-past-the-post voting (FPTP). The second seat is awarded to one of the remaining district candidates so that proportionality is achieved across the region, using a calculation that aims to award parties their seats in the districts where they had their strongest performances.

A mixed electoral system or mixed-member electoral system combines methods of majoritarian and proportional representation (PR). The majoritarian component is usually first-past-the-post voting (FPTP/SMP), whereas the proportional component is most often based on party-list PR. 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.

The mixed ballot transferable vote (MBTV) refers to a type of vote linkage-based mixed-member electoral system where a group of members are elected on local (lower) tier, for example in single-member districts (SMDs). Other members are elected on a compensatory national (upper) tier from a list and voters cast a single ballot where they may indicate their preferences separately.
