Well, there is a sense in which that is true, but it isn’t the one that Labour supporters would wish for. The concrete Miliband proposals – which were presumably kept few in number so as to guarantee headline coverage – were so thin and obviously ill-thought-out that they should scarcely have been worthy of rebuttal. Threatening an energy price freeze years in advance would obviously damage investment in the industry and give rise to an immediate increase in charges. Not to mention the inconvenient truth that cutting the energy companies’ profits would reduce the amount of tax revenue they produce for a government drowning in debt. Then there was the seizing of property from its legal owners who were not doing what the state wanted them to do with it, which would involve either payment of enormous compensation from a government that is already broke or a forcible confiscation of private assets unprecedented in peacetime. This speech was a game-changer all right but only in the sense that it locked Labour into a position that Mr Cameron should relish. All the indications are that he knows this. And that does not necessarily mean – contrary to the mad squawking of headless chickens racing in circles around the Tory farmyard – that he is complacent.
