This book investigates the historical development and enduring influence of progressivism in American political thought and practice, particularly as it shaped the concept of the 'new democracy'. Sidney M. Milkis, a distinguished scholar of American political thought, draws upon extensive archival research and primary source materials to analyze how progressive ideas, originating in the late 19th and early 20th centuries, have continuously reshaped the American presidency and the broader relationship between the government and its citizens. The work argues that progressivism, far from being a static ideology, has evolved into a dynamic force that continues to define contemporary debates about the role and scope of government in a democratic society.

This work is recognized as a significant scholarly contribution to the understanding of American political development, particularly concerning the enduring legacy of progressivism. Scholars have noted its rigorous historical analysis and its insightful framing of how progressive ideals have shaped modern American governance and the presidency. The book is considered essential reading for those seeking to understand the historical roots of contemporary political debates about the role of government.
