“Corbyn’s lasting legacy should be to build all that; create the framework; train the cadres; cement anti-neoliberal economics into the heart of the party’s thinking, and write the principles of a 21st century radical social democracy into the programme, the constition and the practice of the party.”

I agree that this should be the legacy of any left wing leader. Unfortunately, I do not think that Corbyn has the intellectual capacity, vision, logistical nous, organisational ability or political flexibility to achieve this. He has neither the gravitas nor the charisma to persuade dissenters of the left wing approach to society and politics.
