Mixed electoral system in the context of "Mixed-member majoritarian representation"

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 portion of a legislature is elected using one method, while another portion is elected using a different method, with all voters participating in both. Thus, the final results are produced by filling the seats using each system separately based on the votes, then adding the two sets of results together.

A system is called fusion (not to be confused with electoral fusion) or majority bonus, if it is an independent mixture of two system without two tiers. Superposition (parallel voting) is also not the same as "coexistence", in which 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.

Regular elections in Albania are mandated by the Constitution and legislation enacted by Parliament. The Parliament (Kuvendi) has 140 members elected for four-year terms. The president is elected by parliament.

The current Electoral Code of Albania (2024) provides the legal framework for conducting parliamentary elections in the country. The electoral system is a mixed electoral system combining closed and open list proportional representation. There are 12 multi-member constituencies corresponding to the country's 12 administrative regions. Under the 2024 amendments to the Electoral Code, party lists are divided into two parts: one-third of the candidates are placed on a closed list determined by party leadership, while two-thirds are subject to open list preferential voting. A national electoral threshold of 1% is also applied. As of 2024, the code also enables Albanian citizens living abroad to vote by mail in parliamentary elections.

A majority bonus system (MBS, also called a minority-friendly majoritarian 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.

The size of the majority bonus can vary substantially, is usually a fixed number of seats, and may be conditional on the number of votes for each party. However, a relatively small majority bonus (such as in the reinforced proportionality system of Greece) may not always guarantee that a single party can form a government. At the same time, as the majority bonus is allocated in a non-compensatory manner, if the majority bonus is as high as 50%, and the largest party which has 50% of the popular vote receives it, this party may win as many as 75% of all seats available. This differentiates it from the similar majority jackpot system.

In political science, coexistence involves different voters using different electoral systems depending on which electoral district they belong to. This is distinct from other mixed electoral systems that use parallel voting (superposition) or compensatory voting. For example, the rural-urban proportional (RUP) proposal for British Columbia involved the use of a fully proportional system of list-PR or STV in urban regions, combined with MMP in rural regions.

Coexistence of electoral systems exist in multiple countries, like the Democratic Republic of the Congo and Panama, as well as for elections of the European Parliament.. Historically, variants have been used in Iceland (1946–1959), Niger (1993, 1995) and Madagascar (1998).

Mixed-member proportional representation (MMP or MMPR) 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.

In typical MMP systems, voters get two votes: one to decide the representative for their single-seat constituency, and one for a political party, but some countries use single vote variants. Seats in the legislature are filled first by the successful constituency candidates, and second, by party candidates based on the percentage of nationwide or region-wide votes that each party received. The constituency representatives are usually elected using first-past-the-post voting (FPTP). The nationwide or regional party representatives are, in most jurisdictions, drawn from published party lists, similar to party-list proportional representation. To gain a nationwide representative, parties may be required to achieve a minimum number of constituency seats, a minimum percentage of the nationwide party vote, or both.

An 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 (an electoral citizens' list, or civic list). 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.

Electoral lists are required for party-list proportional representation systems.

The 1994 electoral reform in Japan was a change from the previous single non-transferable vote (SNTV) system of multi-member districts (MMD) to a mixed electoral system of single-member districts (SMD) with plurality voting and a party list system with proportional representation. The reform had three main objectives: change the one-party dominance of the Liberal Democratic Party (LDP) from the previous 1955 system to a two-party system with alternation in power, reduce the cost of elections and campaigns, and change campaign focus from individual-centered to party-centered.

Closed list describes the variant of party-list systems where voters can effectively vote for only political parties as a whole; thus they have no influence on the party-supplied order in which party candidates are elected. If voters had some influence, that would be called an open list. Closed list systems are still commonly used in party-list proportional representation, and most mixed electoral systems also use closed lists in their party list component. Many countries, however have changed their electoral systems to use open lists to incorporate personalised representation to their proportional systems.

In closed list systems, each political party has pre-decided who will receive the seats allocated to that party in the elections, so that the candidates positioned highest on this list tend to always get a seat in the parliament while the candidates positioned very low on the closed list will not. However, the candidates "at the water mark" of a given party are in the position of either losing or winning their seat depending on the number of votes the party gets. "The water mark" is the number of seats a specific party can be expected to achieve. The number of seats that the party wins, combined with the candidates' positions on the party's list, will then determine whether a particular candidate will get a seat.

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 is 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 (such as parallel voting) 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.

With MSV, voters usually cast their single vote for a local candidate in a single-member district (SMD) and then all votes (or just the wasted votes, depending on the system) from this lower tier are added to distribute seats between upper tier candidates, typically national party lists. How proportional the outcome is depends on many factors including the vote transfer rules (which votes are recounted as party list votes), whether there is a seat linkage, and other parameters (e.g. the number of list seats) used in the system. MSV systems originate from Germany and variations are currently used in Bolivia, Lesotho and Hungary for local elections in larger municipalities.
