'With each new wave of immigrants, the United States must assess whether social cohesion and national identity continue to thrive. In a thoughtful, empirically rich assessment of racial and ethnic group attitudes in the early twenty-first century, Citrin and Sears offer a confident assessment that immigration, diversity, and a growing national respect for multicultural values do not undermine a strong attachment to the nation.' Louis DeSipio, University of California, Irvine
