An electoral system is the set of rules that determines how votes are cast, counted, and translated into legislative seats or executive officeholders. Because these rules dictate how political power is allocated, they profoundly influence party dynamics, campaign strategies, and the representativeness of a government.

Electoral systems are generally categorized into three main families: Majoritarian/Plurality, Proportional Representation, and Mixed Systems.

1. Majoritarian and Plurality Systems ("Winner-Take-All")

These systems are designed to produce a clear winner for a specific seat, often favoring two-party dominance and stable, single-party governments.

• Plurality (First-Past-the-Post): The candidate with the most votes in a district wins the seat, even if they do not receive an absolute majority (over 50%).
  
  

  • Examples: United States (Congressional), United Kingdom, Canada.

• Majority (Two-Round System): If no candidate wins an absolute majority in the first round, a runoff election is held between the top candidates.
  
  

  • Examples: France (Presidential/Legislative).

• Ranked-Choice (Instant Runoff): Voters rank candidates by preference. If no one reaches a majority, the lowest-performing candidate is eliminated, and their votes are redistributed to the voters' next choices until a majority winner emerges.
  
  

  • Examples: Australia (House of Representatives), Alaska and Maine (U.S.).

2. Proportional Representation (PR)

PR systems aim to ensure that the percentage of seats a party wins in the legislature closely matches the percentage of the popular vote they received. These systems often result in multi-party legislatures and coalition governments.

• Party-List PR: Voters choose a party (or candidates within a party list), and seats are awarded to parties based on their total vote share.
  
  

  • Closed Lists: The party determines the order of candidates.

  • Open Lists: Voters can influence which specific candidates from the party list get elected.

• Single Transferable Vote (STV): A form of PR used in multi-member districts where voters rank candidates. Candidates who meet a specific "quota" of votes are elected, and surplus votes are transferred to other preferred candidates.
  
  

  • Examples: Ireland, Malta.

3. Mixed Systems

Mixed systems combine elements of both majoritarian and proportional methods to capture the perceived benefits of both: local geographic representation and party-wide proportionality.

• Mixed-Member Proportional (MMP): Voters usually have two votes: one for a local district candidate (majoritarian) and one for a political party (proportional). The party vote determines the total number of seats a party receives in the legislature, with "leveling seats" added to ensure proportionality.
  
  

  • Examples: Germany, New Zealand, Scotland
