Yep, they are are a weird bunch.
Ed looks like he has had somebody else's mouth grafted onto his lower jaw but even if he looked normal he would still be a joke. It's worth checking out PMQs every Wednesday to watch him get clowned by Cameron. Week in, week out he gets owned. I can't imagine he has a long-term future as Labour leader.
As for Balls, he will never be accepted by the electorate. He keeps saying "Look" and "Listen" as the start of his sentences which never goes down well. The other thing that weirds me out about him is he looks like he has Down's Syndrome.
I do see this as an opportunity for the Coalition, though. They can do a campaign based on "All Labour Chancellors are mongs, want another?"
That should get them another 5 years.
