I reached out to Nicholas [Rheubottom], the former ED of IDEA and asked why he's running for a party with a platform of "all Nicholas's achievements are shit" and he said, essentially, that it's really valuable to be in a room of people that you disagree with about policy, and he doesn't agree with the whole motion as written.
One might wonder why, if it's valuable to have a bunch of independent voices in a room, working out the best policy - the existing system of council - he's working so hard to make sure we don't have that, and only focus on partisanship.
