Introduction to Plurality and Approval Voting
Plurality voting, also known as first-past-the-post, is a simple electoral system where each voter selects one candidate, and the candidate with the most votes wins, often leading to a winner without majority support. Approval voting allows voters to select any number of candidates they approve of, with the candidate receiving the highest total approvals declared the winner, promoting broader consensus. Both systems influence electoral outcomes differently, impacting voter strategy, representation, and the likelihood of vote splitting.
Key Differences Between Plurality and Approval Voting
Plurality voting selects the candidate with the most votes, while approval voting allows voters to approve multiple candidates, with the highest total approvals winning. Plurality voting often leads to vote splitting and strategic voting, whereas approval voting reduces vote splitting and better captures voter preferences. The key difference lies in how votes are cast and counted, influencing election outcomes and voter satisfaction.
How Plurality Voting Works
Plurality voting selects a winner by counting only the top choice votes each candidate receives, with the candidate securing the most votes declared the winner, regardless of whether they have a majority. This system often leads to strategic voting, where voters choose the most viable candidate rather than their true preference to avoid "wasting" votes. Plurality voting can result in vote splitting and does not account for voter preferences beyond their first choice.
How Approval Voting Works
Approval voting allows voters to select all candidates they find acceptable, rather than choosing just one, which contrasts with plurality voting where only the single most preferred candidate is chosen. Votes in approval voting are tallied by counting the total approvals each candidate receives, and the candidate with the highest number of approvals wins. This system reduces the spoiler effect and tends to promote more consensus candidates compared to plurality voting.
Advantages of Plurality Voting
Plurality voting simplifies the electoral process by allowing voters to select only their top choice, which often leads to quicker vote counting and straightforward results. This system tends to promote stable majority governments, reducing the likelihood of fragmented legislatures or coalition complexities. Plurality voting encourages clear, decisive outcomes that can enhance political accountability and voter engagement.
Advantages of Approval Voting
Approval voting allows voters to select all candidates they find acceptable, increasing the likelihood of electing broadly supported winners and reducing the spoiler effect common in plurality voting. This system encourages honest voting without fear of wasting votes, leading to more accurate representation of voter preferences. Studies show approval voting tends to promote consensus candidates and can decrease polarization compared to plurality voting systems.
Disadvantages of Plurality Voting
Plurality voting often leads to the spoiler effect, where similar candidates split the vote, allowing a less popular candidate to win. It tends to discourage voter expression by forcing people to choose their top candidate rather than indicating support for multiple acceptable options, reducing overall voter satisfaction. This system can also perpetuate a two-party dominance, marginalizing smaller parties and limiting political diversity.
Disadvantages of Approval Voting
Approval voting can lead to strategic voting where voters may approve of only their top choice to avoid helping a less preferred candidate, reducing sincere expression of preferences. It may also encourage the election of compromise candidates who lack broad strong support but are acceptable to many, potentially neglecting majority preferences. Furthermore, the lack of ranking in approval voting can obscure voters' intensity of preference, making it harder to distinguish between strong and weak support among candidates.
Real-World Applications and Case Studies
Plurality voting, widely used in U.S. congressional and local elections, often leads to two-party dominance and vote splitting, as seen in the 2000 U.S. presidential election controversy. Approval voting, implemented in Fargo, North Dakota, and St. Louis, Missouri, allows voters to select multiple candidates, reducing spoiler effects and increasing voter satisfaction. Case studies from these cities demonstrate higher voter turnout and more representative election outcomes compared to traditional plurality systems.
Which Voting System Is More Effective?
Approval voting often proves more effective than plurality voting by allowing voters to select all candidates they find acceptable, reducing vote splitting and better reflecting voter preferences. Plurality voting, where each voter selects only one candidate, can lead to spoiler effects and less representative outcomes in multi-candidate races. Studies indicate that approval voting increases the likelihood of consensus winners and decreases strategic voting, enhancing overall electoral fairness.
