Tony Abbott got away with his howler on the effects of carbon taxes on electricity prices. But, in a piece of poetic justice, he’s now been tripped up by his ignorance of the technical issues underlying his broadband policy, not nearly as bad a piece of intellectual laziness, in my view, but enough to cement the (correct) impression that he is not across the details of key policy issues. To be fair, he doesn’t pretend to be: he offers simplistic slogans to the voters because that’s all he is capable of understanding. In the US, such self-confessed ignorance is a pre-requisite for political success, at least on the right. It seems we are heading the same way.
