One of the hallmarks of conservative commentary over the past few years has been the impressive ability of right-wing pundits to adhere to several different and contradictory caricatures of President Obama without suffering the slightest hint of cognitive dissonance.To the conservative mind, the president can be, depending on the situation, a bumbling dupe who is completely outmatched by the demands of the office (see: any foreign policy issue), or he can be a brilliantly devious schemer who delicately manipulates the machinery of government to achieve his nefarious ends (see: the IRS scandal).
