Interest Groups in the German Bundestag: Exploring the Issue Linkage between Citizens and Interest Groups

Do interest groups adjust their activity in response to public opinion? While previous studies have primarily focused on the link between voters, political parties and governments, interest groups have largely been ignored. This article therefore examines how public opinion affects interest group activity. It is argued that interest group activity is a bottom–up process in which interest groups respond to the issue priorities of citizens. Bringing together panel data on citizen concerns with longitudinal data on interest group issue attention, this article examines the issue linkage between citizens and interest groups in Germany from 1984 until 2010 in two different policy domains. Based on a time-series cross-section analysis, it is shown that issue attention of citizens precedes the registration of interest groups in the Bundestag indicating that interest groups play an important role in issue evolution and political representation.
