Posh Dave - like a rabbit in the headlights.

Just imagine: you are crossing the road. Suddenly, out of nowhere, a car swings round the corner and heads toward you. Rather than run, you do something rather silly: you just stand there and wait as you zoom towards being flattened to the size of a grease spot. Watching Posh Dave on the televison last night, it struck me that this is what he is doing now. He is standing, rooted to the spot, as the inevitable doom of his premiership rumbles inexorably towards him. Every day brings a new indignity and fresh humiliation. Last week, for example, it was the ignomy of being summoned to appear before Parliament by Labour in a manner that he is definitely more used to dishing out rather than being on the receiving end of. Today, it's trying to put a positive spin on the disastrous poll results of yesterday.

After the rout of his Councillor activist base, he will feel the pain, and receive the anger, of many Conservative MP's. He may get some cold comfort from the Boris Johnson win in London but there is a view that he needs to be cautious. Rather than emboldening and empowering Cameron, Johnson's win may give Posh Dave's critics a huge boost. They will say, not without justification, that Johnson won despite, not because of Cameron, and he did so by pushing an agenda that is clearly distinctive to that of the government. Furthermore, while many Londoners do see Johnson as a toff and a Mayor for the rich, his victory shows to Conservatives that you can overcome that stigma and still win an election. Compare this with Posh Dave's extreme difficulty in ridding himself of this Achilles Heel.

But let's not be under any illusions. The Conservative Party has proven itself to be pretty brutal over its leaders in the past and will act swiftly and decisively once the best part of it is convinced it needs too. Generally speaking, as far as most Tory members are privately concerned, they were born to govern and rule the country and will deal with any obstacle to that. By contrast, privately, many Labour Party members feel they were born to storm the gates of heaven and change the world. An unpopular leader for them therefore, is something of a challenge worth undertaking and a secretly delightful two-fingered salute to the status quo. Ed Milliband lives to fight for a while longer!

No way exists for Mr Cameron to come out of Thursday's elections a winner. Ultimately, all he can do now is watch and wait…..
