Intensifying economic and political inequality poses a dangerous threat to the liberty of democratic citizens. Mounting evidence suggests that economic power, not popular will, determines public policy, and that elections consistently fail to keep public officials accountable to the people. McCormick confronts this dire situation through a dramatic reinterpretation of Niccolò Machiavelli's political thought. Highlighting previously neglected democratic strains in Machiavelli's major writings, McCormick excavates institutions through which the common people of ancient, medieval and Renaissance republics constrained the power of wealthy citizens and public magistrates, and he imagines how such institutions might be revived today. It reassesses one of the central figures in the Western political canon and decisively intervenes into current debates over institutional design and democratic reform. McCormick proposes a citizen body that excludes socioeconomic and political elites and grants randomly selected common people significant veto, legislative and censure authority within government and over public officials.
