You are being incredibly judgemental. His leadership was merely fortuitous, he only put himself forward as an alternative - I don't think he ever expected to win, and II don't think he was psychologically prepared. Basically you're criticising him for not being ruthless enough with his political enemies or protecting himself , and those around him, I agree, interests. Perhaps he was never moulded for leadership but I think you seem to forget the incredible alliance of his own MPs, the government and the media all totally against him, has any leader of a party in the UK in modern times faced the opposition and calumny that Corbyn has?

And he's still there, it would have been enough to put most folks of his age off any effort to continue. And as I said, his constituents continue to support him, and perhaps for Corbyn this is the most important thing of all?
