Divided America: The Ferocious Power Struggles in American Politics. By Earl and Merle Black. New York: Simon & Schuster, 2007. 286p. $26.00.

Earl and Merle Black have delivered another insightful book that describes contemporary politics by examining historical trends. They argue that the proper understanding of American politics—from election to policy—requires a regional analysis. In their own words: “Important geographical divisions, we believe, are at the heart of the very close national battles between Democrats and Republicans. American politics becomes much more interesting—and easier to understand—when the party battles are examined region by region” (p.xi). Their five regions are the South, Northeast, Pacific Coast, Midwest, and Mountains/Plains.
