Brother Liddle asks "Why is it unravelling for Dave?" and, while this may be a mild exaggeration, it's true that, in as much as he can ever look jaunty, there's a spring in Gordon's step right now. Perhaps, Labourites dare to dream, the worst is over? Maybe. One poll showing the Tory lead cut to just six points is a pretty shoogly nail upon which to hang your hopes. Nevertheless, the story of the day is this alleged mini-revival. In the end it may be no more than a dead cat bounce, but, just for a moment, let's assume it's not. So, how to explain it?
Firstly, Labour's core vote may be firming up. Some waverers have returned to the comfort of the fold. Secondly, this mini-revival, if it even exists, is a proof of Gordon's predicament, not proof that the worst is past.
