Book excerpt: If federalism is about protecting the states, why not listen to them? In the last decade, the Supreme Court has reworked significant areas of constitutional law with the professed purpose of protecting the dignity and authority of the states, while frequently disregarding the states'' views as to what federalism is all about. The Court, according to the states, is protecting federalism too much and too little. Too much, in striking down federal law where even the states recognize that a federal role is necessary to address a national problem. Too little, in inappropriately limiting state experimentation. By listening more carefully to the States, the Supreme Court could transform its federalism jurisprudence from a source of criticism and polarization to a doctrine that should win broad support from across the political spectrum. In this important book, six distinguished authors redefine federalism and reaffirm Justice Louis Brandeis's vision of states and localities as the laboratories of democracy.
