The complete collapse of the administration’s credibility has led to a baroque profusion of conspiracy theories, but there is another reason why almost any screwy hypothesis can get traction in these later days. The administration is full of people who love intrigue and skullduggery. The propensity of excitable bloggers to detect plots is matched by the right-wing propensity to hatch them. The ruling Republicans are the same people, after all, who cooked up Watergate and Iran Contra. They like that sort of thing; and, between the Straussian doctrine of premeditated dissimilation and the general glorification of political crime as machismo, they have found a wonderfully elastic excuse to do whatever they want and lie about it with a good conscience. So one shouldn’t be too hard on the conspiracy theorists. Discovering complicated schemes is surely no nuttier than contriving them. There’s more than one way to acquire a tin-foil hat.
