This study examines whether rising polarization in Americans’ partisan judgments has positive implications for political participation. Drawing on cross-sectional and panel survey data, we find evidence that polarized judgments are related to pre-election intent to vote, as well as to post-election self-reported voter turnout. Polarized evaluations also predict greater reporting of participation in campaign activities beyond voting. Polarization in candidate evaluations consistently has more of an impact than affective polarization. However, our results suggest that polarization in evaluations of both parties and candidates includes an expressive component that does not necessarily translate into political action. Roughly one-quarter to one-third of the actual change in turnout can potentially be attributed to polarization in evaluations of Republican and Democratic presidential candidates.

两极分化对政治参与的影响：仇恨对方会激励选民吗？

这项研究检验了美国人党派判断中日益加剧的两极分化是否对政治参与有积极影响。利用横断面调查和面板调查数据，我们发现有证据表明，两极分化的判断与选举前的投票意愿以及选举后自我报告的选民投票率有关。两极分化的评估还预测，除了投票之外，还会有更多关于参与竞选活动的报道。候选人评估中的两极分化始终比情感两极分化具有更大的影响。然而，我们的结果表明，对两党和候选人的评价两极分化包括一个不一定转化为政治行动的表达成分。
