Federalism is one of the most influential concepts in modern political discourse as well as the focus of immense controversy resulting from the lack of a single coherent definition. Malcolm M. Feeley and Edward Rubin expose the ambiguities of modern federalism, offering a powerful but generous treatise on the modern salience of the term. “Malcolm Feeley and Edward Rubin have published an excellent book.” —Sanford Levinson, University of Texas at Austin “At last, an insightful examination of federalism stripped of its romance. An absolutely splendid book, rigorous but still accessible.” —Larry Yackle, Boston University “Professors Feeley and Rubin clearly define what is and is not federal system. This book should be required for serious students of comparative government and American government.” —G. Ross Stephens, University of Missouri, Kansas City “Feeley and Rubin have written a brilliant book that looks at federalism from many different perspectives—historical, political, and constitutional. Significantly expanding on their earlier pathbreaking work, they have explained the need for a theory of federalism and provided one. This is a must read book for all who are interested in the Constitution.” —Erwin Chemerinsky, Duke University School of Law
