Corbyn won because the other contestants were middle-of-the-road non-entities who did not stand for any principles they really believed in. Like most parties at the moment, they do market research to see what should go down well and then pay lip service to it and it is hollow. We need politicians who actually believe in something and fight for it, regardless of what the opinion polls say. I don't like eveything Corbyn says - I agree with some, disagree with other things - but at least he is saying something he believes in. The others are piss-poor and that Liz Kendall is a bloody joke. Their reaction to Corbyn was not to put forward policies to counter, it ws to just stand whining in the corner. Pathetic.
