'This book stands for many things, including a very deep and broad understanding of federalism at work in immigration policies, and the role of ethnic antipathy and ugly nativism in the inception of so many present day anti-immigrant policies and narratives. But it also stands for the value in having talented collaborators with different disciplines and literatures - political science and the law - for this is a prime example of how the sum can be greater than even the individual scholarly efforts. Gulasekaram and Ramakrishnan's model of polarized change has considerable explanatory power, and the work is a fascinating narrative.' Michael A. Olivas, author of No Undocumented Child Left Behind: Plyler v. Doe and the Education of Undocumented Schoolchildren
