According to a popular but controversial view in contemporary party research, political parties increasingly put a premium on governing within the institutions of the state rather than on representation of interests and identities in society. This critique has been phrased most uncompromisingly in Richard Katz and Peter Mair’s theory of the cartel party, according to which the cartel party governs but does not represent, and thus fails to do what we expect of parties in a modern democracy. This article is an analysis and critique of this presupposition, which has largely escaped the attention of commentators. The idea that the cartel party governs but does not represent rests on an untenable view of political representation. As I argue, the normative problem with the cartel party is not so much that this type of party does not represent, as to decide when and how it does or does not represent.
