As America rushes headlong into a dramatic campaign season, it is clear that these consequential contests - and the ones that follow - will be hugely influenced by recent changes in the nation's makeup. "Red, Blue, and Purple America" provides a clear and nuanced understanding of the geographic and demographic changes that are transforming the United States and how that transformation is reshaping politics, for the 2008 elections and beyond. The invaluable result is a detailed picture of current trends as well as a clear-eyed assessment of how they will shape American politics and policy during the next two decades. An elite group of demographers, geographers, and political scientists analyze rapidly changing patterns of immigration, settlement, demography, family structure, and religion.Each analysis describes one major trend and assesses its likely impact on politics, for the 2008 elections but for the long term as well. The authors then lay out the most likely implications for public policy. In doing so, they show how these trends have shaped the Red and Blue divisions we are familiar with today, and how the developments might break apart those blocs in new and surprising ways.
