Using an array of data and analysis, the book shows that fears about immigration fundamentally influence white Americans’ core political identities, policy preferences, and electoral choices, and that these concerns are at the heart of a large-scale defection of whites from the Democratic to the Republican Party. The authors demonstrate that this political backlash has disquieting implications for the future of race relations in America. White Americans’ concerns about Latinos and immigration have led to support for policies that are less generous and more punitive and that conflict with the preferences of much of the immigrant population.
