Duffy, Robert J. The Green Agenda in American Politics: New Strategies for the Twenty-First Century. Lawrence: University Press of Kansas, 2003.
Organizations such as the Sierra Club and Friends of the Earth are familiar to anyone with an interest in environmental protection. As activist groups, they played by the same rules for years. But in 1994, the rules changed. With the Republican takeover of Congress, environmental groups faced sweeping changes in federal policies that threatened the enforcement of environmental laws. As these organizations intensified their efforts to meet these challenges, they also altered their electoral strategies and political spending patterns. This book traces those actions and shows what they mean for the future of environmentalism in the political arena. — University Press of Kansas website.
