Yeah, that's about my feeling as well Andy - with the possible exception of Rail, which I think could probably be done if it was pitched correctly to the public.
Corbyn doesn't have the political capital (or the judgement) to do that, though. It's very disheartening as I am sympathetic to many of his policy goals, but his lack of judgement is going to get the party slaughtered and hand power to the Tories until I am an old man.
At present his only ghost of a chance is a) some massive unforeseen PR disaster for the Tories, and it would have to be very serious; b) May seriously cocking up in the TV special. And I mean cocking up on the level of insulting an audience member's grandma or having a breakdown and smothering herself in peanut oil or something.
