"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and willto the best of my Ability, preserve, protect and defend the Constitution of the United States."
When reading the oath and the "to the best of my Ability" qualifier I think a good case can be made that the buck does not stop at the oval office for #(44+1). There is no responsible party in the office! As an analogy: If parents let their eight-year-old drive their car, knowing full well that he is not competent to do this and it is pretty much certain that he may harm himself and others, they will be held accountable for accidents that are caused by the non-qualified driver at the wheel. Transferring this to #(44+1) a lot of the responsibility lies with the Congress men and women, and Senators, who keep the non-qualified "driver" behind the wheel. Whatever their motivations are, they MUST be held accountable by their constituents for their irresponsible support!
