The Political Dynamics of Partisan Polarization [Paperback]

The Element offers a theory of party identification, explaining why Republicans and Democrats become real-life, ideological partisans.This Element has three objectives: to identify and explain why some Republicans and Democrats have polarized, particularly over the last twenty years; to demonstrate that they have done so not on this or that issue but systematically, programmatically; and to bring into the open profound asymmetries in polarization between the two parties.This Element has three objectives: to identify and explain why some Republicans and Democrats have polarized, particularly over the last twenty years; to demonstrate that they have done so not on this or that issue but systematically, programmatically; and to bring into the open profound asymmetries in polarization between the two parties.This is a study of the dynamics of partisan polarization in the United States. It has three objectives: (1) to identify and explain why some Republicans and Democrats  but not others  have polarized, particularly over the last twenty years; (2) to demonstrate that they have done so not on this or that issue but systematically, programmatically  domain versus issue sorting; and (3) to bring into the open profound asymmetries in polarization between the two parties, not least that Republicans polarized early and thoroughly on issues of race, while Democrats in the largest number stayed neutral or even conservative until only recently. Emerging from the reasoning and results is a revised theory of party identification that specifies the conditions under which ordinary Republicans and Democrats can become ideological partisans  real-life conservatives and liberals in their behavior  in the choices they make on candidates, policies, and parties.1.
