Hale and Landy frame their defense of the Constitution by understanding America in terms of modernity, where small republics are no longer possible and there is a need to protect the citizens of a massive modern state while still preserving liberty. The Constitution makes large, popular government possible by placing effective limits on the exercise of power. The Constitution forces the people to be governed by the dead, both to pay the debt we owe to those who came before us and to preserve society for generations yet unborn.
The central argument of Keeping the Republic is that the Constitution provides for a free government because it places effective limits on the exercise of power--an essential ingredient of any good government, even one that aims to be a popular government. That the people should rule is a given among republicans; that the people can do anything they want is a proposition that no one could accept with their eyes wide open. Thus, the limits that the Constitution place on American political life are not a problem, but a solution to a problem.
Hale and Landy offer both a survey of American anti-constitutionalism and a powerful argument for maintaining the constitutional order of the nation's Framers.
