Working draft - please direct comments and suggestions to Suzanne Robbins. Thank you.


This paper seeks to expand upon what we know regarding the structure of interest group networks. To explore the potential for Social Network Analysis in the larger context of group behavior and information sharing, we make use of existing federal contribution data to explore how non-corporate political action committees are linked to one another at the federal level via regulated campaign finance. Thus, we explore the density of networks, who the central players are and group relationships with respect to investment behavior. Here, we make use of FEC contribution data from the 2000 electoral cycle to describe and explore the relationships between the different types of contributions made to federal candidates.
