For the past several years, Mark Silk and Andrew Walsh have presided over an ambitious, richly textured study of religion and regional variations in the United States. Their findings, which are nicely distilled in this summary volume, point out the importance of geography and regional cultures in decoding both the nation's religious life and its political behavior. I commend this book to anyone seeking to understand the complex mosaic of religious life in America. -- Randall Balmer, Columbia University

This book not only confirms what we already suspect, but goes much further in detailing regional religious differences and how they influence American politics. For general readers, the message is clear: Beware broad generalizations about religion and politics in the United States. For politicians, preachers, and pundits seeking to mobilize the populace one way or another, the message is crucial: Overlook regional views of religion and of its relation to politics at your peril. -- Wade Clark Roof, University of California, Santa Barbara

With the clarity of its analyses and its demonstration of how important the nation's diverse religious regions are―for social mores, for politics, for religion itself―One Nation, Divisible is a splendid and much-welcomed study. -- Mark Noll, University of Notre Dame

The authors create a most compelling mosaic of this phenomenon through their use of history and personal stories. Excellent notes, bibliography, index. Recommended. ― CHOICE

Includes a fascinating final chapter that revisits American history through the prism of regional religious affiliation. This scholarly work will appeal mostly to historians and political scientists, but it will also inform citizens and officials who want to gain insight into the often ignored role of religion in American society. ― Foreword Reviews

One Nation, Divisible is a masterful account of the potent nexus of religion and region in the United States. Silk and Walsh offer an insightful retelling of the American national story through the lenses of piety and place. -- John C. Green, University of Akron

It doesn't happen very often but on occasion books surprise and even delight you for their perspicuity, and the persuasive nature of their argument. Mark Silk and Andrew Walsh's One Nation, Divisible: How Regional Religious Differences Shape American Politics does just that. Regional differences in religion and politics matter in America, but showing it and doing it with data, interpretation and occasional pithiness is welcome. I found Silk and Walsh's analysis fresh, unique, and determinative for the case that they make: regional differences matter, both in terms of religious majorities in each region and the unique regional and cultural ecologies.

Mark Silk and Andrew Walsh's excellent One Nation, Divisible presents a valuable corrective should any of us forget the reality and importance of regionalism in American religion or regionalism's consequences for religion and politics and politicians. The authors' regionalist perspective is fascinating, and it is a pleasure to read how fully and skillfully these articulate authors develop this theme in their book. -- Robert Booth Fowler, University of Wisconsin, Madison ― Politics and Religion
