Hippykin, your comment about people voting for Blair not Labour is an interesting one. However, your second point I do not agree with. You believe New Labour will drift back to middle-left, but I think the most notable point at the moment is that new labour has actually gone further over to the right. It has spend the last few years trying to persuade dissallusioned ex-Tory voters to support them instead, and in doing so has stopped being the Labour Party.
They were, historically, a party for the common man, but their current policies are not thus. I know its a widely used example, but the removal of the 10p tax band is a clear case of this.
No workers party would remove the band that helps the poor, whilst reducing the taxes for the upper and (most noticeably) middle classes. These are not New Labour, they are New Tory.
Perhaps after this public showing of mistrust they will think back to what the party stands for, and make a decision. They can continue to target the middle classes and steal Tory votes, or alternatively the party can realign and try to regain the lower class votes on which it is built.
Oh, and I don't think Boris is a buffoon. He speaks from the heart, and puts in little 'jokes' here and there, which are often very funny. However, because he does these things and answers freely, he makes mistakes. Many politicians will hear a question, then repeat it slightly misquoting, allowing them to answer the question they wanted to hear.
And anyway, even if he is a buffoon, it can't be that bad: look at Bush. To quote the Hitchhiker's Guide to the Galaxy:
"Anyone who is capable of getting themselves made President should on no account be allowed to do the job"
