This episode of Civics 101 explores the roots and consequences of the United States two-party system by comparing American democracy with political systems around the world. The hosts, Nick Capodice and Hannah McCarthy, consult comparative politics experts Guillermo Rosas and Robin Best to understand why the US is nearly unique in having only two dominant parties. They examine Duverger's law, single-member district plurality voting, and how the winner-take-all structure squashes third parties while forcing massive umbrella coalitions. Along the way, they analyze multi-party setups in Germany and proportional representation in Spain, weighing the trade-offs between voter choice and government stability.
