Replication Data for: Basking in Their Glory? Expressive Partisanship among People of Color Before and After the 2020 U.S. Election

As the number of people of color (PoC) grows in the United States, a key question is how partisanship will develop among this important electoral group. Yet many open questions remain about PoC partisanship, due to limited availability of panel data, a lack of sensitive instrumentation, and small samples of PoC in most public opinion surveys. This brief report leverages a unique panel of African American (N=650) and Latino (N=650) eligible voters, before and after the 2020 Presidential Election between Democrat Joe Biden and Republican Donald Trump. Using measures that tap expressive partisan, racial, and national identity attachments, we find that Biden’s electoral victory significantly intensified partisan identity among his Democratic PoC supporters, relative to PoC who were not Democrats and supported Trump. We do not find significant changes in racial or national identities. Our results advance research on PoC's partisanship.

随着美国有色人种（People of Color, PoC）人口持续增长，这一重要选举群体的党派倾向将如何发展，已成为核心研究议题。然而，由于多数民调中有色人种面板数据（panel data）可获得性不足、敏感测量工具匮乏，且有色人种样本量偏小，学界对有色人种党派倾向的认知仍存在诸多未决问题。本研究简报依托一套独特的面板数据集，涵盖2020年美国总统大选（民主党候选人乔·拜登与共和党候选人唐纳德·特朗普对阵）前后的1300名合格选民，其中非洲裔美国人（African American）、拉丁裔（Latino）各650名。研究采用能够捕捉表达性党派、种族与国家身份依恋的测量指标，结果显示：相较于未加入民主党且支持特朗普的有色人种选民，拜登的胜选显著强化了其民主党支持者的党派认同；研究未观测到种族或国家身份出现显著变化。本研究结果推动了有色人种党派倾向领域的相关研究。
