I’m like totally with Rune Engelbreth here: The opposition wants an election because polls show that the opposition will win an election and the government doesn’t want an election because polls show that the government will lose an election. A Categorical Imperative Fail, in other words.
But: Why can’t government and opposition say what they really want to say?
Well, because arguing from benefits to actors is illetigimate, arguing from benefits to the society is legitimate – and the only way to appeal to other actors. But by arguing from benefits to society, the arguments become insincere. A problem which troubles a lot of politics, but I can’t see it being solved.
