Recent U.S. elections have defied nationwide majority preference at the White House, Senate, and House levels. This work of interdisciplinary scholarship explains how “winner-take-all” and single-member district elections make this happen, and what can be done to repair the system. Proposed reforms include the National Popular Vote interstate compact (presidential elections); eliminating the Senate filibuster; and proportional representation using Ranked Choice Voting for House, state, and local elections.
