ABSTRACT
This chapter surveys the existing literature on geographic political segregation in the United States at both the state and county level, demonstrating that Americans increasingly live in states and communities that regularly provide landslide victories to one of the two major parties. This chapter also provides an overview of the kinds of communities that tend to become overwhelmingly Republican and Democratic as well as the kinds of people you tend to find in such communities. It also surveys the literature indicating that this trend will have important consequences for American democracy.
