How do Asian Americans think about their ethnic origin? How do ethnic identities affect political preferences? Drawing on interviews with a diverse group of Asian Americans, I provide a nuanced understanding of how they think about their ethnic origin and pan-ethnic identities. The findings reveal that ethnicity plays a significant role in shaping electoral preferences, as Asian Americans exhibit coethnicity preferences, conditional on partisanship. Moreover, I uncover several factors that have been underexplored in the existing literature, including transnational ties, news consumption, and political preferences on foreign policies related to their home country. This article provides a more comprehensive and nuanced understanding of Asian American identities by showing that the ethnic origin roots of Asian Americans can have significant influence on their political interests and candidate preferences.
