Types of electoral systems and their effects

Electoral systems are the rules and methods used to conduct elections and determine winners. These systems influence how political parties form, how representatives are chosen, and the level of accountability to voters. Different systems serve various regime objectives, such as promoting broad representation or ensuring stability through fewer parties.

Proportional representation

Proportional representation allocates seats in the legislature based on the proportion of votes each party receives. As a result, it often leads to more political parties being represented, which can increase the election of minority groups and women candidates by giving smaller parties a chance to gain seats.

Single-member district plurality systems

In this approach, each district elects one representative, and the candidate with the most votes wins, even without a majority. This tends to create two-party systems because smaller parties struggle to win districts. It provides strong constituency service (support and representation for local voters) since there's one representative per district, and it ensures geographic representation by linking representatives to specific areas.

These systems reflect a balance between broad inclusivity and focused accountability, with proportional systems encouraging diversity and plurality systems promoting stability.

Presidential election rules in different regimes

Presidential elections vary across regimes in how they determine winners, often requiring either a plurality (the most votes, but not necessarily more than half) or an absolute majority (more than 50% of the votes). These rules can include runoff elections (additional rounds if no candidate wins outright) to ensure the winner has strong support, which provides a national mandate (broad authority to govern based on voter backing).

Rules for determining presidential winners

Different countries use specific rules to achieve regime objectives like federal balance or majority support:

• Mexico - The president is elected by a plurality of the national popular vote, meaning the candidate with the most votes wins, without needing an absolute majority. This simplifies the process but can result in a winner with less than half the votes.
• Nigeria - Candidates must win the most votes nationwide and secure at least 25% of the vote in two-thirds of the states. This reflects Nigeria's federal system (a government structure dividing power between national and regional levels), ensuring the president has support across diverse regions.
• Iran and Russia - Candidates need an absolute majority in the first round or a second-round runoff between the top two vote-getters. This majoritarian approach (requiring a majority to win) gives the winner a stronger national mandate by ensuring broad voter approval.

These variations help regimes balance quick decisions with legitimacy, where runoff systems prevent winners with narrow support.

Role of electoral regulatory organizations

Electoral regulatory organizations are bodies that oversee elections, setting rules for ballot access (who can appear on the ballot) and competition. They can limit or enhance electoral competition (the ability of multiple candidates to vie for votes) depending on regime goals, such as maintaining control or promoting democracy.

Examples of regulatory organizations and their effects

• Iran's Guardian Council - This body excludes candidates who are reform-minded (favoring changes to the system) or do not support Islamic values. As a result, it limits the number of candidates, reduces competition, and restricts representation by controlling who can run.
• Mexico and Nigeria's independent election commissions - Created during democratic transitions (shifts from authoritarian to more open systems), these commissions aim to reduce voter fraud (illegal manipulation of votes) and manipulation. They enhance competition by ensuring fairer ballot access and more transparent elections.

Through these organizations, regimes can either restrict or expand electoral participation to align with their objectives for control or democratization.

Appointment systems in legislative bodies

Some regimes use appointment systems, where leaders select members for legislative bodies instead of electing them. This can promote diversity of viewpoints or advance the agenda of governing elites (ruling groups with power). Appointments often complement elected positions to balance representation.

Appointment processes in different regimes

• United Kingdom's House of Lords - Appointments are approved by the monarch (the king or queen) based on recommendations from the prime minister and an independent commission. This system aims to include diverse expertise and viewpoints in the upper house of the legislature.
• Iran's Guardian Council - Half the members are selected directly by the Supreme Leader (the highest religious and political authority), and the other half are judiciary nominees approved by the Majles (Iran's parliament). This setup advances the agenda of governing elites by ensuring alignment with regime values.
• Russia's Federation Council - Members are appointed by regional governors and legislatures. The president influences this through federal districts (administrative groupings of regions), where presidential envoys (representatives) are appointed, and governors can be selected from president-approved lists. This reasserts central federal power over regions.

These systems show how appointments can either diversify or centralize control in legislatures, depending on the regime's priorities.

Impacts of election rule changes

Changes to election rules can significantly affect how different groups are represented in government. For example, shifting from plurality to proportional systems might increase seats for religious, ethnic, or socioeconomic groups (categories based on faith, heritage, or economic status) by allowing more diverse candidates to win.

Effects on representation and timing:

• Group representation - Rule changes, such as easing ballot access, can lead to better inclusion of underrepresented groups, while restrictive rules might limit their participation and influence.
• Timing of legislative elections - Across countries, election schedules vary based on term-limit policies (rules on how long officials can serve). Some systems have fixed terms, while others allow flexibility, affecting how often voters hold representatives accountable and influencing political stability.

Overall, these changes shape the level of democratization (the degree of democratic practices) by altering who participates and how power is distributed.
