This document provides an outline and details of Chapter 10 on Interest Groups. It discusses what interest groups are, characteristics of effective interest groups, and an evaluation of interest groups. Interest groups represent various segments of society and try to influence government policy outside of elections. Effective interest groups have significant money, membership, access to lawmakers, and focus on single issues. While interest groups are part of democracy, they may disproportionately represent well-organized, wealthy interests over public interests and smaller, less powerful groups.
