I think Labour are having a bit of identity crisis myself, they are tore between the unions that voted Ed in and those that want them to occupy the centre where they have a chance of winning the election.... and of course they have got Ed who doesn't help.
The Green Party do have some radical solutions but they have also some more moderate views as well. As they are unlikely to win an election, I don't fear them bankrupting us, but it might be interesting to see them given chance to interact more with the general public e.g. in live debates. You never know, they might start moderating some of those solutions.
