Voting

In any election, each voter casts one vote for one candidate in a multi-candidate race for multiple offices. Posts are filled by the candidates with the most votes ( plurality voting). Thus, in a three-seat constituency, the three candidates receiving the largest numbers of votes would win office. SNTV, like single transferable vote, can be used with non-partisan ballots.


Example

Three seats are to be filled among five candidates: A, B, C, D and E fielded by 3 parties X, Y and Z. C, D and E are the winning candidates. Thus, Party Z gets two seats and Party Y gets one seat. No one party took all the seats as might have been the result under first past the post or
plurality block voting Plurality block voting, also known as plurality-at-large voting, block 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 sea ...
. But counting the votes by party gives these vote tallies: Party Y has more votes than Party Z, but receives fewer seats because of an inefficient spread of votes across the candidates. If Party Y's two candidates had had more equal vote tallies, it would have won two seats and Party Z only one. Or if Party Z's candidates had received less equal vote tallies, Party Y would have won two seats even if its candidates were not equally popular. (There is more chance in SNTV than a more orderly system of PR.) If either party had risked trying to win all three seats, causing more vote splitting among supporters of Parties Y and Z, then A of Party X might have won a seat and either party Y or Z would then have taken one fewer seat.


Comparison to MNTV

Candidates are running in a 3 member district of the 10000 voters. Under non-transferable (and non-cumulative) voting, voters may not cast a more than one vote for a single candidate. * Under (plurality) block voting, the standard multiple non-transferable vote, voters may cast 3 votes (but do not have to) * Under limited (block) voting, voters may cast 2 votes maximum. * Under the single non-transferable vote, voters may cast 1 vote. Party A has about 35% support among the electorate (with one particularly well-like candidate), Party B around 25% (with two well-like candidates) and the remaining voters primarily support independent candidates, but mostly lean towards party B if they have to choose between the two parties. All voters vote sincerely; there is no tactical voting. * Under the single non-transferable vote (not a type of approval voting), the three most popular candidates according to voters first preferences are elected, regardless of party affiliation. * Under limited voting, it is most likely that the party with a plurality takes two seats (the number of votes each voter has), and the minority party receives the remaining seats. * Under (plurality) block voting, the party with plurality support most likely wins all seats.


Proportional representation

SNTV facilitates minority representation, that is, it produces mixed representation of large and small parties where no party takes all the seats. In fact, SNTV would elect the same people as are elected in STV contests where the vote transfers do not move an initially-lower-placing candidate over an initially-higher-placing one. It is common for STV vote transfers to elect the same as would be elected under SNTV. But not having transfers, SNTV sees more votes wasted than under STV due to the votes placed on un-electable candidate or in surpluses received by successful candidate over and above the quota used in STV elections and not being able to be transferred. SNTV produces representation that is most proportional (

) when political parties have accurate information about their relative levels of electoral support, and nominate candidates in accordance with their respective levels of electoral support or when all parties suffer from poor information of that sort. Knowing the portion of the votes a party can take allows it to avoid vote waste due to lessening the chance of vote splitting and inefficient placement of party support. Under 'perfect' tactical voting and strategic nomination, SNTV would be equivalent to the D'Hondt (Jefferson) method of proportional representation. But under SNTV even inefficient distribution of votes allows more balanced representation than would be elected under either single-member plurality or
Block voting Block voting or bloc voting refers to electoral systems in which multiple candidates are elected at once and a group (voting bloc) of voters can force the system to elect only their preferred candidates. Block voting may be used at large (in a si ...
. Given n candidates to be elected, Candidate A can guarantee success by receiving one more than \frac of the votes (the

), because n other candidates cannot all receive more than Candidate A. But as SNTV is a plurality system, it is possible to win with less than that quota. To determine the successful candidates, candidates' vote tallies are compared with the vote tallies of others. Vote spitting due to poor information on voters behaviour may deny a popular party its due share of representation. (Single Transferable Voting does not suffer from this handicap as votes are transferable and many are transferred and used that are wasted under SNTV.) Parties organizing slates of multiple candidates may nominate many candidates and then learn on election night that the party was not as popular as they thought. If every party does that, all suffer the same inefficiency and the final result is proportional. If one party is more prudent, it may do better than the others. Because votes cannot be transferred, there is more chance of vote wastage than under STV. But in elections that use SNTV, representation is usually mixed. It is rare for one party to make a sweep of a city's seats, a thing common in

votes. The risks of poor strategic nomination are not equal for parties of various strengths. A large party would have much more to lose from the split vote effect than to gain from avoiding the wasted vote effect, and so would likely decide to err on the side of fielding fewer candidates (but probably not less than their existing number of seats). A small party with little representation would be more risk-tolerant and err on the side of too many candidates, hoping to gain as many seats as possible, perhaps even winning more than its proportion of the electorate if they can edge out candidates from larger parties with just a few votes. As well, a small party running just one candidate would not suffer from vote spitting, while a larger party running four or more may suffer from that. SNTV electoral systems, like STV and proportional electoral systems generally, typically produce more proportional electoral outcomes as the size of the electoral districts (number of seats in each constituency) increases.


Potential for tactical voting

The potential for
tactical voting Strategic voting, also called tactical voting, sophisticated voting or insincere voting, occurs in voting systems when a voter votes for another candidate or party than their ''sincere preference'' to prevent an undesirable outcome. For example, ...
in a single non-transferable vote system is large. Casting only one vote, a rational voter wanting to maximize the number of seats captured by his party should vote for a candidate of the party that has a chance of winning, but one that will not win by too great a margin and thus take votes away from party colleagues. This creates opportunities for tactical nominations, with parties nominating candidates similar to their opponents' candidates in order to split the vote. Like all multiple-winner selections, parties find it advantageous to run a range of candidates in SNTV elections. SNTV has been measured through the lens of such concepts as ''decision-theoretic analysis''. Professor Gary W. Cox, an expert on SNTV, has studied this system's use in Japan. Cox has an explanation of real-world data finding the, "two systems lurality and semi-proportionalare alike in their strategic voting equilibria." His research found that voters use the information offered in campaigns (polls, reporting, fundraising totals, endorsements, etc.), to rationally decide who the most viable candidates are and then vote for them. SNTV can result in complicated intra-party dynamics because in a SNTV system, a candidate runs against candidates from their own party as well as against candidates from the other party. SNTV elections are not zero-sum contests. Just because one particular candidate is elected does not mean that another specific candidate will not be. They both can be elected. Because running on issues may lead to a situation in which a candidate becomes too popular and therefore draws votes away from other allied candidates, SNTV may encourage legislators to join factions that consist of patron-client relationships in which a powerful legislator can apportion votes to his or her supporters. In addition, parties will do best if their supporters evenly distribute their votes among the party's candidates. Historically, in

History

Single Non-transferable Voting first proposed in solid form by Saint-Just in 1793 in a proposal to the French National Convention. He proposed having the whole country as one multi-seat district. It was not adopted in France at that time. Japan was the first country to adopt SNTV for election of government members a hundred years later than Saint-Just's proposal. In 1880s Japan adopted SNTV for provincial politicians and in 1900 for national politicians.

, where SNTV is known as ''at-large representation'' ("representación por acumulación" in Spanish), political parties vary the ballot order of their candidates across electoral divisions, in order to ensure each candidate has a roughly equal chance of success. Since most voters choose the candidates placed at the top of their party lists on their ballots, at-large candidates from the same party usually obtain approximately equal vote totals. The two major Puerto Rican political parties, the Popular Democratic Party and the New Progressive Party, usually nominate six candidates for each chamber, while the much smaller

Jordan

SNTV was used in Jordan from 1993 to 2016.

The 1993 electoral reform introduced SNTV as the "one-man, one-vote", which was argued to be a more egalitarian alternative to the former "block vote" (or
