Don’t get me wrong, I am not saying that Labour has no policy, or that its policy is incoherent. My point isn’t even about whether its policy is wrong or right. It’s just that it has made a policy that was already complicated — let’s put up borrowing in order to cut borrowing — even more complicated — we are against the Tory cuts but we accept them.
Complicated messages - even worse, apparently contradictory messages - don't get listened to. And if people aren't listening, they aren't being persuaded.
