"The role of ideology in American politics has been neglected by political scientists and historians in favor of a realist approach, which looks at group, partisan, and constituency interests to explain parties, elections, and policies. In this book, however, Lowi treats ideology as an equal and sometimes superior political force. The account of each of the four ideological traditions is in large part a success story in the affairs of American democracy; each has long occupied a political space within the structure of federalism. But each story is also a tragedy, because each possesses the seeds of its own collapse."@en
