White Americans vary in their self-professed racial and ethnic attitudes and attachments. How then, does this dynamic relate to broader issues in political behavior and psychology? Here, we explore how Americans who possess meaningful ethnic attachments differ from other white Americans who do not express such attachments. The results reveal significant variation in attitudes toward racial resentment, nativism, and authoritarianism between those with strong ethnic attachments and those without. Moreover, we find very substantial differences between respondents on these same outcome measures across the various categories of self-reported racial ideology. These findings strongly imply that treating white Americans as a unified, hegemonic, monolithic analytical category obscures crucial political variation. These variations demonstrate that ignoring the internal diversity of white identity can obscure critical dimensions of political behavior.
