| Most research on interest groups has focused on theoretical perspectives concerning why members join these groups. Missing from this work is any connection between theories of organizational maintenance (i.e., how an organization forms) and research on influence activity (i.e., what an organization does). This article argues that a connection exists between organizational maintenance and the participation of their members in the organization's influence activities. Relying on a two-stage study of educational interest groups and the U.S. Congress, this article maintains that rational choice theories of interest group maintenance cannot account for the presence and perseverance of Washington-based education interest groups. A theory acknowledging levels of ideological commitment may be a more appropriate model for understanding educational interest groups at the national level. |
