Partisan hostility and American democracy : explaining political divisions and when they matter
(Book)

Includes bibliographical references and index.

"Generations of political scientists argue that American politics needs strong, cohesive parties to function effectively. Yet more recently, many worry that such vigorous partisan sentiments--most notably, the rising hostility between the parties--can damage democracy, as partisans willingly undermine the system if it means stopping their disliked opponents. Is this the case? This book offers a nuanced evaluation of when and how partisan animosity matters in today's highly charged--but fluid--political environment, using data from two of the most tumultuous years in recent American history, 2019 to 2021. The authors show that partisan animus powerfully shapes political behaviors, but its effects are conditional, not constant. They develop a theory of the conditions that make partisan animosity most salient, and show that, in the absence of these, other thought processes take over. While partisan animosity makes democratic functioning more difficult (e.g., by politicizing seemingly non-political issues, undermining compromise), it does not inevitably lead to democratic erosion (e.g., the rejection of foundational democratic norms or the endorsement of violence). Partisan hostility has degraded American democracy, but it does not in itself represent an existential threat. The future of democracy depends on how politicians respond to the rise of animosity"--,Provided by publisher.
