I think you are ignoring his plight. Louise Ellman, someone who I both know and have respect for, is currently on the TV saying that he has to deal with this anti semitism. She made a really good point when she said that Corbyn recognises right wing anti semitism but refuses to see left wing anti semitism, and tbh he’s not the only one.
He has had more people either refusing to join the shadow cabinet, or resigning from the Sc or being fired from the Sc than any previous political leader. He is divisive. I agree about Blairites and indeed that absolute cretin Blair himself, but that happens to be the Labour Party. At least Davek recognises that it should be purged to move to what he believes a PLP should look like. His response to the nerve gas was one of defence of Russia, had it been done by the Americans or heaven forbid the Israelis then he would have been screaming it from the rooftops, and his own MP’s recognise this. May, on the other hand was cold and deliberate and has gotten most Western and sensible states to back her up. No one other than Russia would agree with Corbyn. Clutching at straws, I think not.......
