Still Connected? Attitudinal Representativeness of German Party Memberships

In modern representative democracies political parties are the main institutions responsible for providing linkage between citizens and the state. One way to do this is through organizational linkage mechanisms, especially the representation of a party's voters through the party membership. This paper tries to describe the attitudinal representativeness of German party memberships in terms of left-right positions using data from two party membership studies from 1998 and 2009. In a second step, the determinants of divergent attitudes of party members from the position of the parties' voters are analyzed on an individual level, testing four possible explanations for this.
