The unprecedented geographic and socioeconomic mobility of twentieth-century America was accompanied by a major reshuffling of political support in many parts of the country. Yet at the dawn of the new century these local and regional movements are still poorly understood. How can we account for persistent political regionalism and the sectional changes that have radically altered the nation's political landscape, from the Sun Belt to the Rust Belt? Patchwork Nation reveals answers to these vital questions. The masterful analysis in Patchwork Nation reminds us that the traditions and histories of individual states differ widely. Gimpel and Schuknecht's insightful examination of territorial cleavages thus provides us with a key to understanding the raw material that politicians use to fashion our party system. Their findings are an important reminder of geography's central role in our nation's political behavior. From the news analysts and pundits who use maps to identify electoral behavior patterns to the politicians and campaign strategists who study them to locate centers of support, experts of all stripes continue to recognize geography's importance to our political understanding. But in the wake of the survey research revolution of the late twentieth century, scholars often overlooked the relevance of geographic factors for the study of politics. Patchwork Nation retrieves this lost knowledge and extends it in important new directions, encouraging scholars to fundamentally reassess their thinking about the geographic basis of contemporary political behavior.
