Fear and Loathing Across Party Lines: The Polarization of American Politics
Free and open to the public
Current debates over the extent of polarization among the American public focus on the extent to which policy preferences have moved. While 鈥渕aximalists鈥 claim that partisans鈥 views on policies have become more extreme over time, 鈥渕inimalists鈥 respond that the majority of Americans remain centrist, and that what little centrifugal movement has occurred reflects sorting, i.e., the increased association between partisanship and ideology.
I propose an alternative definition of polarization, based on the classic concept of social distance. Evidence from a variety of sources demonstrates that Republicans and Democrats increasingly dislike, even loathe each other. Moreover, partisan affect is only weakly founded in policy attitudes; thus movement in policy attitudes may not explain affective polarization. The more plausible explanation lies in the nature of political campaigns; exposure to messages attacking the out-group only confirms partisans鈥 biased views of their opponents.
