This article is a thought experiment. It constructs ideal types of political representation in the sense of Max Weber. Inspired by Quentin Skinner and others, the aim is to give a rhetorical turn to contemporary debates on representation. The core idea is to claim an ‘elective affinity’ (Wahlverwandschaft, as Weber says following Goethe) between forms of representation and rhetorical genres of their justification. The four ideal types of political representation are designated as plebiscitary, diplomatic, advocatory, and parliamentary, corresponding to the epideictic, negotiating, forensic, and deliberative genres of rhetoric as the respective ways to plausibly appeal to the audience. I discuss historical approximations of each type of representation and apply the combination of representation and rhetorical genres to the understanding of the European Union’s unconventional system of ‘separation of powers’. I conclude with supporting parliamentary representation, based on dissensus and debate, with complements from other types.
