Supplementary Vote System
The contingent vote is an electoral system used to elect a single representative in which a candidate requires a majority of votes to win. It is a variation of instant-runoff voting (IRV). Under the contingent vote, the voter ranks the candidates in order of preference, and the first preference votes are counted. If no candidate has a majority (more than half the votes cast), then all but the two leading candidates are eliminated and the votes received by the eliminated candidates are distributed among the two remaining candidates according to voters' preferences. This ensures that one candidate achieves a majority and is declared elected. The contingent vote differs from IRV which allows for many rounds of counting, eliminating only one weakest candidate each round. IRV allows a small chance the candidate outside the top two can still win. The contingent vote can also be considered a compressed form of the two-round system (runoff system), in which both 'rounds' occur witho ...

Spoiler Effect
Vote splitting is an electoral effect in which the distribution of votes among multiple similar candidates reduces the chance of winning for any of the similar candidates, and increases the chance of winning for a dissimilar candidate. Vote splitting most easily occurs in plurality voting (also called first-past-the-post) in which each voter indicates a single choice and the candidate with the most votes wins, even if the winner does not have majority support. For example, if candidate A1 receives 30% of the votes, similar candidate A2 receives another 30% of the votes, and dissimilar candidate B receives the remaining 40% of the votes, plurality voting declares candidate B as the winner, even though 60% of the voters prefer either candidate A1 or A2. Under such systems vote pairing (also called vote swapping, co-voting or peer to peer voting) can mitigate the effect, but it requires two voters in different districts to agree, and identifying probabilities of candidates winning ...

Single-winner Electoral Systems
A single-member district is an electoral district represented by a single officeholder. It contrasts with a multi-member district, which is represented by multiple officeholders. Single-member districts are also sometimes called single-winner voting, winner-takes-all, or single-member constituencies. A number of electoral systems use single-member districts, including plurality voting (first-past-the-post), two-round systems, instant-runoff voting (IRV), approval voting, range voting, Borda count, and Condorcet methods (such as the Minimax Condorcet, Schulze method, and Ranked Pairs). Of these, plurality and runoff voting are the most common. In some countries, such as Australia and India, members of the lower house of parliament are elected from single-member districts; and members of the upper house are elected from multi-member districts. In some other countries like Singapore, members of parliament can be elected from both single-member districts as well as multi-member dis ...

Single Transferable Vote
Single transferable vote (STV) is a multi-winner electoral system in which voters cast 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, 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. Under STV, no one party or voting bloc can take all the seats in a district unless the number of seats in the district is very small or almost all the votes cast are cast for one party's candidates (which is seldom the case). This makes it different from other district voting systems. In majoritarian/plurality systems such as first-past-the-post (FPTP), instant-runoff voting (IRV; also known as the alternative vote), block voting, and ranked-vote ...

Alternative Vote Plus
The alternative vote plus (AV+), or alternative vote top-up, is a semi-proportional voting system. AV+ was devised by the 1998 Jenkins Commission which first proposed the idea as a system that could be used for elections to the Parliament of the United Kingdom. As the name suggests, AV+ is an Additional Member System which works in two parts: the 'AV' part and the 'plus' part. As in the alternative vote system, candidates are ranked numerically in order of preference. The important difference is that an additional group of members would be elected through regional party lists to ensure a degree of proportionality; in typical proposals, these members are 15–20% of the whole body. More specifically, each voter would get a second vote to elect a county or regional-level representative from a list of candidates of more than one person per party. The number of votes cast in this vote would decide how many representatives from that county or region would go on to parliament. In ...

Types Of Democracy
Types of democracy refers to pluralism of governing structures such as governments (local through to global) and other constructs like workplaces, families, community associations, and so forth. Types of democracy can cluster around values. For example, some like direct democracy, electronic democracy, participatory democracy, real democracy, and deliberative democracy, strive to allow people to participate equally and directly in protest, discussion, decision-making, or other acts of politics. Different types of democracy - like representative democracy - strive for indirect participation as this procedural approach to collective self-governance is still widely considered the only means for the more or less stable democratic functioning of mass societies.Diamond, Larry Jay and Plattner, Marc F.

Tactical Manipulation Of Runoff Voting
In the two-round system, there is potential for both tactical voting and strategic nomination.The Gibbard–Satterthwaite theorem shows that any voting method which does not allow tactical voting must be either dictatorial or non-deterministic (incorporating random elements). A non-deterministic system may not select the same outcome every time it is applied to the same set of ballots, so non-deterministic systems are rarely suggested for public elections. Tactical voting is where voters do not vote in accordance with their true preferences, but instead vote insincerely in an attempt to influence the result. Runoff voting is intended as a method that reduces tactical voting, but two tactics called compromising and pushover are still possible in many circumstances. In particular voters are strongly encouraged to compromise by voting for one of the three leading candidates in the first round of an election. Strategic nomination is where candidates and political factions influence the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History And Use Of Instant-runoff Voting
Instant-runoff voting (IRV) is a voting method used in single-seat elections with more than two candidates. Instead of voting only for a single candidate, voters in IRV elections can rank the candidates in order of preference. Ballots are initially counted for each elector's top choice, losing candidates are eliminated, and ballots for losing candidates are redistributed until one candidate is the top remaining choice of a majority of the voters. When the field is reduced to two, it has become an "instant runoff" that allows a comparison of the top two candidates head-to-head. IRV more commonly known outside the US as the alternative vote or preferential voting, was devised around 1870 by the US architect W. R. Ware. Today it is in use at a national level to elect the Australian House of Representatives, the National Parliament of Papua New Guinea, the President of Ireland and President of India. In Australia it is also used for elections to the legislative assemblies ( lower hou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instant-runoff Voting
Instant-runoff voting (IRV) is a type of ranked preferential voting method. It uses a majority voting rule in single-winner elections where there are more than two candidates. It is commonly referred to as ranked-choice voting (RCV) in the United States (although there are other forms of ranked voting), preferential voting in Australia, where it has seen the widest adoption; in the United Kingdom, it is generally called alternative vote (AV), whereas in some other countries it is referred to as the single transferable vote, which usually means only its multi-winner variant. All these names are often used inconsistently. Voters in IRV elections rank the candidates in order of preference. Ballots are initially counted for each voter's top choice. If a candidate has more than half of the first-choice votes, that candidate wins. If not, then the candidate with the fewest votes is eliminated, and the voters who selected the defeated candidate as a first choice then have their vot ...

Top-four Primary
A top-four primary or top-four ranked-choice voting is an election method using a nonpartisan blanket primary where up to four candidates, those with the most votes, advance from a first round of voting, regardless of the political party. The ''round two'' (general) election, held some weeks later, uses instant-runoff voting (''IRV'', also known as ''ranked-choice voting'', ''RCV'') to confirm a majority winner among the top set of candidates. Its first use was in 2022 Alaska's at-large congressional district special election. It can be seen as a replacement to the ''blanket primary'' which advances only the ''top-two'' candidates. It was first advocated by FairVote in 2012Fixing Top Two in California The 2012 Elections and a Prescription for Further Reform [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonpartisan Blanket Primary
A nonpartisan blanket primary is a primary election in which all candidates for the same elected office run against each other at once, regardless of the political party. Partisan elections are, on the other hand, segregated by political party. Nonpartisan blanket primaries are slightly different from most other elections systems with two-rounds/runoff, aka "jungle primaries" (such as the (Louisiana primary), in a few ways. The first round of a nonpartisan blanket primary is officially the " primary." Round two is the "general election." Round two ''must'' be held, even if one candidate receives a majority in the first round. In addition, there is no separate party nomination process for candidates before the first round. Also, political parties are not allowed to whittle down the field using their internal techniques (such as party primaries or conventions). It is entirely possible that multiple candidates of the ''same'' political party advance to the general election. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
