This article introduces White identity as an understudied concept in Canadian politics and compares how White settlers’ ingroup attachments and their outgroup attitudes—specifically, White settlers’ anti-Indigenous attitudes—shape Canadian politics. We find that White identity is associated with greater support for government spending on policies that disproportionately benefit White Canadians, such as pensions, whereas Indigenous resentment is associated with greater opposition toward government spending on policies that are often perceived as disproportionately benefiting Indigenous peoples, such as welfare. In Canada outside Quebec, both White identity and anti-Indigenous attitudes are associated with voting Conservative. In Quebec, White identity mobilizes support for the Bloc Québécois, while White settlers’ negative attitudes toward Indigenous peoples are not associated with vote choice.

Heeding the call of the special issue, we look at the past decade's advances in public opinion studies of our understanding of the relationship between white racial identities, attitudes, and presidential voting preferences. Following a short review of developments in the literature during the Obama years, we critically evaluated four theories explaining whites' support for Trump: racial resentment, xenophobia, sexism, and white identity. Using data from three ANES studies, we test the relative explanatory power of all four approaches in predicting a vote for Trump during the 2016 Republican primary, the 2016 election, and intent to vote for him in 2020. The results suggest that xenophobia had the most consistent effect across all models, followed by racial resentment and sexism. White identity appears to have influenced voting for Trump in the primary and it could also have an impact in the 2020 election, but its effect in the 2016 general election does not appear to have been consistent with theoretical expectations. Finally, we use these results to think critically about the state of the field and propose new questions and challenges for research.
