If nothing else, understanding this makes it much easier to understand the splits in the party after the recent rebellion within the shadow cabinet. Even the language used by each side reflects basically different conceptions of what politics is about. For Corbyn’s opponents, the key word is always “leadership” and the ability of an effective leader to “deliver” certain key constituencies. For Corbyn’s supporters “leadership” in this sense is a profoundly anti-democratic concept. It assumes that the role of a representative is not to represent, not to listen, but to tell people what to do.
For Corbynistas, in contrast, the fact that he is in no sense a rabble rouser, that he doesn’t seem to particularly want to be prime minister, but is nonetheless willing to pursue the goal for the sake of the movement, is precisely his highest qualification. While one side effectively accuses him of refusing to play the demagogue during the Brexit debate, for the other, his insistence on treating the public as responsible adults was the quintessence of the “new kind of politics” they wished to see.
