Is Ed Miliband a) hopeless, b) on course to become Prime Minister or c) both?

I have never quite understood Ed Miliband’s appeal. He always reminds me of Cuthbert Cringeworthy from The Bash Street Kids. I find it hard to imagine him becoming Prime Minister. Something just feels wrong about that. I’m not alone in wondering about this. Brian Wilson, the former energy minister, wrote yesterday that Miliband still has a kind of credibility problem.
