Merged thread – Unelectable Corbyn and Let's not bomb ISIS

I was struck by the comments of a lady in a Newsnight ‘straw poll’ the other night. She said (to paraphrase) ‘I agree with everything Mr Corbyn said, I think his policies make sense and he is trustworthy, but I of course will not be voting for him in a general election because he is unelectable’

I am interested in the opinion of forumites, as I think we represent a fair cross-section of the country’s thinking on such things.

So, why is Jeremy Corbyn unelectable? The press keep telling us this, but surely if his name is on the ballot paper as a candidate, he is electable? Or is there a law against it that I am not aware of..
