Cameron is not sunk. But we need to know what his Britain would be like…

The Conservative leader needs to get his mojo back. At least he had some to start with, mojo not being a quality much associated with his predecessors: ‘That often elusive quality that sets a person apart from everyone else. The word “magic” could, almost without exception, replace it in all of its contexts, sentences or applications.’ So says urbandictionary.com and it should know.

Yet something has gone wrong with Dave’s magic. We are approaching the point when the Conservative chances at the next election will either crystallise or begin to break apart. Having risen to 37-38 per cent in the polls, Mr Cameron is drifting downwards — well away from the 41 per cent minimum he needs to contend for victory. Some of this is ‘Brown bounce’ but not all. The end of the ‘phoney war’ with Tony Blair gives the Tories their best chance yet to define their election bid more clearly.
