This chapter explores the mixed relationship between democratic innovation and advocates, such as associations and interest groups. On the one hand, advocates bring important knowledge, experience, and networks to democratic reform by representing and promoting their particular interests to decision makers and the broader public. Yet, on the other hand, many of the attributes and practices of advocacy sit in tension with the procedural rules and deliberative ideals of particular democratic innovations, such as mini publics. The chapter discusses various formal and informal roles that advocates play in and around democratic innovations. Nothwithstanding these roles current practices of democratic innovation pose challenges to the practice of advocacy; they provide little room for partisan perpsectives, and can appear overly structured and exclusive. Greater attention needs to be paid to possible opportunities to innovate in the activities of advocacy, but to do this requires understanding democratic innovation beyond discrete participatory forums.
