has the other foot dropped?

In all the talk I've seen about the Labour Party (UK) and its leadership election, one question that seems to me a screamingly obvious one to ask has hardly been brought up at all: to what extent does the booming of Jeremy Corbyn's candidacy, now culminated with his election, resemble the election of Michael Foot as party leader in 1980? On this unanswered question hangs what my reaction to it will be.

None of the news analysis pieces I've seen addresses this question at all. ( But I'm going to. )
