"Obamacare Wars shows how the laws intergovernmental structure, which entails the participation of both the federal government and the states, has deeply shaped the politics of implementation. Focusing on the creation of insurance exchanges, the expansion of Medicaid, and execution of regulatory reforms, Daniel Béland, Philip Rocco, and Alex Waddan examine how opponents of the ACA fought back against its implementation. They also explain why opponents of the law were successful in some efforts and not in othersand not necessarily in a seemingly predictable red vs. blue pattern. Their work identifies the role of policy legacies, institutional fragmentation, and public sentiments in each instance as states grappled with new institutions, as in the case of the exchanges, or existing structures, in Medicaid and regulatory reform. Looking broadly at national trends and specifically at the experience of individual states, Obamacare Wars brings much-needed clarity to highly controversial but little-understood aspects of the Affordable Care Acts odyssey, with implications for how we understand the future trajectory of health reform, as well as the multiple forms of federalism in American politics"--Publisher's website.
