Abstract: U.S. historical accounts of partisanship recognize its competitive nature and its inherent, latent threat of violence, but social scientific conceptions of partisan identity developed in quiescent times have largely missed that dangerous dimension. We rebalance scholarly accounts by investigating the national prevalence and correlates of 1) partisan moral disengagement that rationalizes harm against opponents, 2) partisan schadenfreude in response to deaths and injuries of political opponents, and 3) explicit support for partisan violence. In two nationally representative surveys, we find large portions of partisans embrace partisan moral disengagement (10-60%) but only small minorities report feeling partisan schadenfreude or endorse partisan violence (5-15%). Party identity strength, social sorting, and trait aggression are related to each type of extreme party view.  We conclude with reflections on the risks of radical partisanship in democratic politics, even as parties continue to serve as essential bedrocks of democracy.
