Democracy establishes relationships of political equality, ones in which citizens equally share authority over what they do together and respect one another as equals. But in today's divided public square, democracy is challenged by political thinkers who disagree about how democratic institutions should be organized, and by antidemocratic politicians who exploit uncertainties about what democracy requires and why it matters. This title mounts a bold and persuasive defense of democracy as a way of making collective decisions, showing how equality of authority is essential to relating equally as citizens. It explains why the US Senate and Electoral College are urgently in need of reform, and discusses proportional representation, racial vote dilution and gerrymandering, wealth inequality, and judicial review as a support to the democratic ideal. What emerges is an emphatic call to action to reinvigorate our ailing democracies, and a road map for widespread institutional reform.
