libterm.com Mixed-member proportional (MMP) voting combines the benefits of proportional representation with single-member district elections, ensuring that parties receive a fair share of seats corresponding to their overall vote share while maintaining local representation. This system helps balance voter influence between individual candidates and party platforms, reducing wasted votes and promoting diverse political participation. Discover how MMP can impact your voting experience and shape democratic fairness throughout this article.
Table of Comparison

Introduction to Electoral Systems
Mixed-member proportional (MMP) combines single-member district representation with proportional representation to balance individual candidate accountability and party fairness. Open list systems allow voters to influence the order of party candidates on the list, enhancing voter choice within proportional representation frameworks. Both systems aim to improve electoral fairness but differ in voter impact on candidate selection and party proportionality.
Overview of Mixed-Member Proportional (MMP)
Mixed-Member Proportional (MMP) is an electoral system combining first-past-the-post and party-list proportional representation to balance constituency representation with overall proportionality. Voters typically cast two votes: one for a local candidate and one for a political party, ensuring that the total number of seats a party receives corresponds to its share of the party vote. MMP aims to reduce disproportionality seen in plurality systems by adjusting the allocation of list seats to compensate for discrepancies in constituency outcomes.
Key Features of Open List Systems
Open list systems allow voters to influence individual candidate selection within party lists, increasing voter choice and candidate accountability. Unlike mixed-member proportional systems, open lists do not combine district and party vote proportions, but rely solely on voter preferences for candidates to determine seat allocation within party totals. These features enhance personalized voting and often result in more intra-party competition and candidate responsiveness.
Representation: MMP vs Open List
Mixed-member proportional (MMP) voting combines single-member district representatives with party list seats to ensure overall proportionality, giving minority parties a better chance at fair representation. Open list systems allow voters to influence which party candidates receive seats, promoting intra-party competition and personalized candidate support. MMP generally balances individual accountability and proportional party representation more effectively than open list systems, which can sometimes favor popular candidates over balanced party distribution.
Voter Choice and Ballot Structure
Mixed-member proportional (MMP) systems combine single-member districts with party-list proportional representation, giving voters two votes: one for a candidate and one for a party, enhancing voter choice by allowing separate preferences for individual candidates and overall party strength. Open list systems allow voters to choose individual candidates within party lists, directly influencing candidate ranking and promoting personalized voter impact on party seat allocation. MMP ballots typically feature dual sections for candidate and party selections, while open list ballots focus on ranked or marked candidate choices within a single party list.
Party Influence in Both Systems
In mixed-member proportional (MMP) systems, party influence is strong as parties control candidate lists for proportional seats, shaping overall legislative representation through party ranking. Open list systems allow voters greater influence by enabling them to reorder or select individual candidates within party lists, reducing centralized party control but maintaining party proportionality in seat allocation. Both systems balance party power and voter choice, with MMP emphasizing party-determined lists and Open lists enhancing candidate-level voter input.
Impact on Political Diversity
Mixed-member proportional (MMP) systems enhance political diversity by combining single-member district representation with proportional seat allocation, allowing smaller parties to gain seats reflective of their overall vote share. Open list systems also promote diversity by permitting voters to influence candidate order within party lists, which can increase representation for minority viewpoints and internal party factions. Both systems tend to reduce dominance by major parties and encourage multiparty cooperation, contributing to more pluralistic legislative bodies.
Advantages of Mixed-Member Proportional
Mixed-Member Proportional (MMP) systems combine direct candidate elections with party list proportionality, ensuring both local representation and overall proportional fairness, reducing wasted votes and improving voter satisfaction. MMP offers a balanced approach by allowing voters two votes--one for a local representative and one for a party--enhancing voter choice and accountability. This system mitigates distortions common in first-past-the-post systems while maintaining connection between constituents and their representatives, fostering more equitable and stable legislative outcomes.
Benefits of Open List Voting
Open list voting empowers voters to influence the order of candidates on party lists, enhancing democratic choice and personal accountability. This system promotes greater voter engagement by allowing the selection of preferred individual candidates rather than just parties. Consequently, open lists tend to increase political competition within parties, fostering candidate responsiveness and diversity.
Conclusion: Choosing the Right System
Choosing between Mixed-member proportional (MMP) and Open list systems depends on balancing proportional representation and voter influence on candidate selection. MMP ensures overall proportionality by combining direct district winners with party list seats, benefiting smaller parties and reflecting voter preferences more accurately. Open list systems allow voters greater control over candidates within party lists but may lead to less proportional outcomes, making MMP preferable for achieving fair representation in diverse electorates.
