This volume examines the actual impact of interest groups on members of Congress. Based on interviews with a broad sample of membership of the House of Representatives, the study makes it clear that the situation is more complex than is normally realized and that the influence of lobbies is often exaggerated. The research focuses on the critically important question of the response to lobbying activity.Originally published in 1966.A UNC Press Enduring Edition -- UNC Press Enduring Editions use the latest in digital technology to make available again books from our distinguished backlist that were previously out of print.
