Types of party members and their implications: Results from a survey of Portuguese party members

Scholars have emphasized the decline of party membership and a decrease in party activism. Yet these general patterns hide a diversity of party members with distinct profiles, attitudes and behavior. Using Portugal as a case study, this article examines the heterogeneity of party members based on the different motivations for joining the party and distinct levels of involvement. The findings support previous typologies that distinguished between more activist versus more passive party members. The results also suggest that different party types present a distinct proportion of the two types of affiliates. In addition, these two types of members display distinct levels of ideological congruence with the party.
