When taking office, the President does not swear to create jobs. He does not swear to “grow the economy.” He does not swear to institute “fairness.” The only oath the President takes is this one:
I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.
By sending — literally — brownshirted enforcers to engage in — literally — a midnight knock at the door of a man for the non-crime of embarrassing the President of the United States and his administration, President Obama violated that oath. You can try to pretty this up (It’s just about possible probation violations! Sure.), or make excuses or draw distinctions, but that’s what’s happened. It is a betrayal of his duties as President, and a disgrace.
