'This book is an original, nuanced, and exquisitely-researched critique of the Whiggish 'ideology of progress' narrative that dominates post-New Deal scholarship on American politics, constitutional law and development, civil liberties and civil rights, and the Supreme Court. Kersch's path-breaking alternative explanation of constitutional development will make this book an award-winner. It is a must read for political scientists, historians, legalists, the informed public, as well as for scholars of constitutional development – within and without the American context. I recommend it for use in graduate and undergraduate courses on American politics and political development, civil liberties and civil rights, constitutional law and politics, and comparative constitutional change.'
