If there is one thing that characterizes American politics today it is the idea that leftists are idiots. This, of course, is a long-term derivative of the original idea, formulated in the late forties, which was that leftists are traitors. The original charge has been endlessly repeated, worked over, softened, even sublimated so to speak, so that now it seems benign: oh yes, the leftist, still in the playpen, the charming but no longer dangerous idiot of American politics. Given the widespread assumption that the real action in American politics lies in the struggles between “realistic,” “mature,” “problem-solving” “progressives” and Neanderthal Republicans, one has to wonder why it is so important for defenders of Obama to scapegoat leftists. Why, in other words, they have to explain that there are “limits” to what any President can do, that it is “necessary to compromise,” that previous periods of reform also had “fits and starts,” as if they were speaking to children who know nothing of politics, history and human nature.
