I have to hand it to Corbyn, given that since day 1 people have been trying to overthrow and undermine him, he's hung on pretty admirably. I know if I was in his shoes I would have gone "fuck it, you lot figure it out" long before now. I think he's done okay and held on to more than he should have, considering the organised character assassination attempts from the media, the Tories, and his own party.
But fine, bin him. There's nobody waiting in the wings who will unite the PLP and the membership, so Labour are still fucked in 2020.
