Book excerpt: The Political Theory of a Compound Republic presents the essential logic of James Madison and Alexander Hamilton's design of limited, distributed, constitutional authority proposed inThe Federalist. Two revised and expanded ensuing chapters show how the idea of constitutional choice has been employed since the adoption of the 1789 Constitution of the United States. A new concluding chapter questions commonly accepted beliefs about sovereign nation-states and considers governance from the perspective of twenty-first century 'citizen-sovereigns.'
