Voting Systems: Electoral Design and Representation

The United States uses a first-past-the-post (FPTP) single-member district system for nearly all elections, combined with a unique Electoral College for presidential elections. This system tends to produce two dominant parties, makes third-party representation difficult, and can result in governments where the winning party receives fewer total votes than the opposition.

Germany uses a mixed-member proportional (MMP) system for Bundestag elections, combining single-member districts with proportional representation party lists. Voters cast two ballots—one for a district candidate and one for a party—with proportional seats allocated to ensure overall parliamentary representation matches the party vote. New Zealand adopted a similar MMP system in 1996, replacing its prior FPTP model.

The United Kingdom uses FPTP for House of Commons elections but has adopted proportional and preferential systems for devolved assemblies and European elections. Sweden uses a party-list proportional representation system with a 4% threshold, producing multi-party coalitions and high levels of proportional representation. Several U.S. cities and Alaska have adopted ranked-choice voting, but the national system remains overwhelmingly FPTP.
