This edited collection of original commissioned essays tells the important story of how interest groups and PACs (Political Action Committees) from business, labor, and other activist organizations have worked with the changing rules governing lobbying and "sea change" provided by the Republican Revolution in 1994 to try to achieve their particular goals. This book shows how Congress and interest groups have interacted, how the current system works, and how certain changes may affect these relationships in the future. The essays, describing the lobbying tactics of business groups like AT&T, labor groups like AFL-CIO, and membership groups like The Sierra Club are written by accomplished political scientists who tell the stories in compelling and provocative ways, and describe how each group has handled the changes under the New Republican Congress. Anyone with an interest in campaigns, elections, and Congress.
