Alternative vote plusThe 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.
Dual-member proportional representationDual-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.
Bullet votingBullet voting, also known as single-shot voting and plump voting, is a voting tactic, usually in multiple-winner elections, where a voter is entitled to vote for more than one candidate, but instead votes for only one candidate. A voter might do this because it is easier than evaluating all the candidates or as a form of tactical voting. Voters can use this tactic to maximize the chance that their favorite candidate will be elected while increasing the risk that other favored candidates will lose.
Pouvoir législatifvignette|L'Assemblée nationale, chambre basse du Parlement français. Le pouvoir législatif est, dans la théorie de la séparation des pouvoirs de Montesquieu appliquée aujourd'hui dans les régimes démocratiques, l'un des trois pouvoirs constituant un État, avec : le pouvoir exécutif ; le pouvoir judiciaire. Il est en général chargé de voter la loi, de gérer le budget de l'État, et selon les pays de contrôler l'action du pouvoir exécutif et judiciaire. Le plus souvent, il est exercé sous la forme d'un parlement.
Electoral listAn electoral list is a grouping of candidates for election, usually found in proportional or mixed electoral systems, but also in some plurality electoral systems. An electoral list can be registered by a political party (a party list) or can constitute a group of independent candidates. Lists can be open, in which case electors have some influence over the ranking of the winning candidates, or closed, in which case the order of candidates is fixed at the registration of the list.
Counting single transferable votesThe single transferable vote (STV) is a proportional representation voting system that elects multiple winners based on ranked voting. Under STV, an elector's vote is initially allocated to his or her most-preferred candidate. Candidates are elected (winners) if their vote tally reaches quota. After this 1st Count, if seats still remain open, surplus votes are transferred from winners to remaining candidates (hopefuls) according to the surplus ballots' next usable back-up preference.
