In a time of increasing campaign costs and decreasing state political party activity, legislative party campaign committees have grown to play a major role in the politics of elections in a large number of American states. Anthony Gierzynski's book focuses on these committees.In this first multi-state analysis, Gierzynski explores the nature and practices of the committees through interviews with legislative leaders and staff and through statistical analyses of campaign finance data from ten representative states.In addition to direct cash contributions, legislative caucus campaign committees provide candidates with a multitude of support and services and usually target their resources on close races where they will have the greatest impact. Leadership PACs, the campaign committees of individual legislators, also allocate their resources strategically.The existence of such committees and the fact that the caucus campaign committees resemble political parties in both structure and behavior leads Gierzynski to pose interesting normative and practical questions. The answers to such questions have major implications for political parties and legislative politics.
