Convincing Congress: 
Understanding Interest Group Strategies in the U.S. Congress
Abstract
To understand the legislative strategies of interest groups, one must account for the legislative context in which groups lobby.  Previous studies of interest group strategies explain interest group behavior by examining the size, wealth, and organizational structure of groups.  In this project, I assume interest groups are strategic actors in a larger legislative game.  I develop a spatial model of interest group participation that describes how and under what circumstances interest groups lobby the US Congress.  I show that groups attempt to change the legislative policy space in three potential ways:  change the policy preferences of members of Congress, change the dimensions of the policy space, or change the docket on which bills are considered.  Groups engage in these three strategies based on a calculus of the costs associated with a strategy.  As the costs of action increase, groups are less likely to participate in the legislative process.  I test these expectations using a unique sample of interest groups that lobbied the 106th House.  Using survey and interview data from interest groups that lobbied in four House committees (and their subcommittees) I test hypothesis about group participation in specific lobbying tactics using maximum likelihood estimation (probit).  The research design and analysis allow for a direct association between an interest group, the issue in which it is interested, and a legislative bill in the US House.  The findings show the most support for the changing preferences model of interest group action.  A case study of two bills shows that group characteristics alone do not explain interest group behavior; rather one must account for the strategic context of legislation to explain interest group behavior.
