I don't think the class composition of Corbyn's vote is too easy to understand.
Some commentators have claimed he represents a profoundly middle class movement, but some of this analysis is based on NRS ABC1 social gradings—gradings which put any office clerical worker in as "middle class" but a business-owning tradesperson in as "working class", for example.
On the other hand, the projected redistributive impact of Labour's manifesto was much less progressive than the Lib Dems, so that's interesting.
For me though, the very different thing about UK Labour in 2017 is the fact it has 800,000 members. Four times the Conservatives even before the huge boost after the recent general election.
That's why the current moment for Labour is something significant, and that's why Corbyn's campaign performed so well and why we should continue to pay attention to him. His campaign has taken place on communications terrain outside the control of the mainstream press, and that's opened up some possibilities.
