Blagojevich and Obama/Bush's New Deal

Economist Steve Horwitz asks the obvious question

I simply do not understand how those who are in favor of giving government all of these new powers because they sincerely believe that doing so will work out the way their blackboard designs intended can keep a straight face. What kind of cognitive dissonance must it take to believe that the people YOU are handing power over to are "not like" Ted Stevens or Rod Blagojevich? How deeply must one be in denial or engage in rationalization to believe that they are "different?"
