A Theory of Geographic Partisan Sorting
This chapter will provide an overview of the existing literature on migration, considering different theories of migration, noting the varying weight given to variables such as economics and community satisfaction in different models of migratory behavior. It will continue with a brief examination of contemporary trends in migratory behavior in the United States. To build the case that politics is now a consideration of many potential migrants, it will survey the most recent literature on political polarization in the U.S. electorate. It will also discuss how political scientists have studied migration and discuss the existing research on politics, migration, and geographic sorting. It will conclude by arguing that the political science and demography literature provide a compelling argument for politically motivated migration and partisan segregation.
