Washington think tanks such as the Brookings Institution, the American Enterprise Institute, and the Heritage Foundation have become so numerous and so influential in recent years that they now constitute virtually a new branch of the political system. In this engrossing and lively book, David M. Ricci brilliantly explores the social, economic, and political trends that have transformed government in Washington and led to the development and prestige of these public policy research centers. "An incisive look at the rise of think tanks and at their impact on policy-making." -- Kirkus Reviews
