The only one of the many, many things people have said that rings true to me is "Michael Foot couldn't win, and he's no Michael Foot." Which digs to the heart of the matter, if you're a supporter. I'm in favour of the policies (well, most of them), but Corbyn is no leader. He still hasn't managed to regularly engage his brain before his mouth, despite 20+ years as an MP - which tells me he never will be, either. If he manages to win, it will be entirely due to those around him and some massive own-goal from the Tory side. Personally, I see it as Milliband all over again. I hope it's not Foot and the SDP all over again.
