Political fragmentation is the fragmentation of the political landscape into different parties and groups, which makes it difficult to deliver effective governance. [1] Political fragmentation can apply to political parties, political groups or other political organisations.
One aspect of political fragmentation can be measured by effective number of parties. [2]
Scholars, journalists and politicians have theorized about a number of potential effects of political fragmentation. For example, it has been argued that higher fragmentation allows voters to better represent their political spectrum of political positions. The length of government coalition formation has also been argued to increase with number of parties and decreases with preexisting political groups. [3] The strength of these effects has been hypothesized to depend on whether it is the government or the opposition that are fragmented. [4] However, the political fragmentation of parliaments has little causal effect on a number of dimensions of the quality of democracy. [5]
The veto player theory predicts that higher fragmentation relates to gridlock, [6] while other literature does not observe increased gridlock. [7]
The political fragmentation, represented by effective number of parties, is roughly estimated with the seat product model, [8] [9] and increases with district magnitude and assembly size. The Duverger's law predicts majoritarian elections with district magnitude of one favor a two-party system and proportional representation increases the number of parties. In proportional representation, higher electoral thresholds reduce number of parties represented while increasing wasted vote. Fragmentation tends to moves toward an equilibrium, regardless of the type of voting system. [10]
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.
The politics of Spain takes place under the framework established by the Constitution of 1978. Spain is established as a social and democratic sovereign country wherein the national sovereignty is vested in the people, from which the powers of the state emanate.
The electoral threshold, or election threshold, is the minimum share of all the votes cast that a candidate or political party requires to achieve before they become entitled to representation or additional seats in a legislature. This limit can operate in various ways, e.g. in party-list proportional representation systems where an electoral threshold requires that a party must receive a specified minimum percentage of votes, either nationally or in a particular electoral district, to obtain seats in the legislature. In single transferable voting, the election threshold is called the quota and it is possible to pass it by use of first choice votes alone or by a combination of first choice votes and votes transferred from other candidates based on lower preferences. In mixed-member-proportional (MMP) systems the election threshold determines which parties are eligible for top-up seats in the legislative body.
In political science, a multi-party system is a political system in which multiple political parties across the political spectrum run for national elections, and all have the capacity to gain control of government offices, separately or in coalition. Apart from one-party-dominant and two-party systems, multi-party systems tend to be more common in parliamentary systems than presidential systems and far more common in countries that use proportional representation compared to countries that use first-past-the-post elections. Several parties compete for power and all of them have a reasonable chance of forming government.
The D'Hondt method, also called the Jefferson method or the greatest divisors method, is an apportionment method for allocating seats in parliaments among federal states, or in proportional representation among political parties. It belongs to the class of highest-averages methods.
First-past-the-post voting is an electoral 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 plurality voting (SMP) 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.
A party system is a concept in comparative political science concerning the system of government by political parties in a democratic country. The idea is that political parties have basic similarities: they control the government, have a stable base of mass popular support, and create internal mechanisms for controlling funding, information and nominations.
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 legislative body. 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.
At a national level, Greece holds elections for its legislature, the Hellenic Parliament.
Consociationalism is a form of democratic power sharing. Political scientists define a consociational state as one which has major internal divisions along ethnic, religious, or linguistic lines, but which remains stable due to consultation among the elites of these groups. Consociational states are often contrasted with states with majoritarian electoral systems.
The Labour Campaign for Electoral Reform (LCER) is an organisation formed of members and supporters of the British Labour Party, who are interested in issues of democratic renewal and electoral reform.
A plural society is defined by Fredrik Barth as a society combining ethnic contrasts: the economic interdependence of those groups, and their ecological specialization. The ecological interdependence, or the lack of competition, between ethnic groups may be based on the different activities in the same region or on long–term occupation of different regions in the Defined by J S Furnivall as a medley of peoples - European, Chinese, Indian and native, who do mix but do not combine. Each group holds by its own religion, its own culture and language, its own ideas and ways. As individuals they meet, but only in the marketplace in buying and selling. There is a plural society, with different sections of the community living side by side, within the same political unit.
In politics, gridlock or deadlock or political stalemate is a situation when there is difficulty passing laws that satisfy the needs of the people. A government is gridlocked when the ratio between bills passed and the agenda of the legislature decreases. Gridlock can occur when two legislative houses, or the executive branch and the legislature are controlled by different political parties, or otherwise cannot agree.
The Royal Commission on the Electoral System was formed in New Zealand in 1985 and reported in 1986. The decision to form the Royal Commission was taken by the Fourth Labour government, after the Labour Party had received more votes, yet it won fewer seats than the National Party in both the 1978 and 1981 elections. It was also a reaction to the power displayed by Prime Minister Robert Muldoon, whose action of illegally abolishing the Superannuation scheme in 1975 without any repercussions highlighted the need to distribute power in a more democratic way. The Royal Commission's report Towards a Better Democracy was instrumental in effecting New Zealand to change its electoral system from first-past-the-post to mixed member proportional.

He is also an Affiliated Professor at the University of Haifa. Shugart specializes in electoral systems, party systems, and the design of political institutions, primarily through empirical studies of political systems across large numbers of countries. Shugart is also an orchardist, and runs the Fruits and Votes blog on electoral systems and fruit growing.
The effective number of parties is a concept introduced by Laakso and Taagepera (1979) which provides for an adjusted number of political parties in a country's party system. The idea behind this measure is to count parties and, at the same time, to weight the count by their relative strength. The relative strength refers to their vote share effective number of electoral parties (ENEP) or seat share in the parliament effective number of parliamentary parties (ENPP). This measure is especially useful when comparing party systems across countries, as is done in the field of political science. The number of parties equals the effective number of parties only when all parties have equal strength. In any other case, the effective number of parties is lower than the actual number of parties. The effective number of parties is a frequent operationalization for the political fragmentation.
Electoral reform is a change in electoral systems which alters how public desires are expressed in election results.
Direct representation or proxy representation is a form of representative democracy where voters can vote for any candidate in the land, and each representative's vote is weighted in proportion to the number of citizens who have chosen that candidate to represent them.
In voting theory, the micromega rule holds that, when political parties choose electoral systems, "the large prefer the small and the small prefer the large". The term "micromega" references Micromégas, a tale by Voltaire in which dwarfs and giants dialogue.
