The contrast between the normative functions of political parties in representative democracies and their empirical working is stark and rapidly increasing. This article starts from a sober, realist account of the empirical state of affairs and from structural problems of democracy and participations – in terms of limits of time, information, qualification and relevant expertise – that have to be acknowledged by any realist–utopian proposal of alternatives beyond the exclusive alternative of ‘thin, realist democracy’ or emphatic ‘strong, participatory, direct, or (...) mass democracy’. We can do better. My search for institutional alternatives looks not for the replacement of political parties but for their relief. Many, not all, of their normative tasks can be shared with other functional networks, associations and organizations. In exploring such a new division of political labour I draw on older debates and designs of associative democracy and on recent discussions to democratize expertise and to expertise democracy in order to address urgent societal problems of high-risk decisions under conditions of extreme complexity, contingency, unpredictability and uncertainty and deep contestedness of our knowledge, problems that turn out to be unmanagable by party politics and representative democracy.
