The one group of members overlooked in nearly all dissections of Corbynism are the existing members switching from whoever they supported in 2015 to Jeremy. We're not talking people who joined to vote last summer and have stayed, but comrades who've knocked about the block ( as well as a few doors) and have served the party in various capacities. I know this party constituency exists because, a)
I'm one of those people, and b) so are nearly all my comrades. I know folks who voted Andy, Yvette, and Liz last time who are all hitting the Corbyn button on this occasion. It's not that Jez has so much won them over, but rather the behaviour of his opponents have driven their support into the arms of his campaign. Jeremy hasn;t attracted them, the political geniuses of core group hostile, you know, the people supposedly specialising in reaching out beyond bases and comfort zones,
lost them.
