The President's Oath

Each and every President of the United States has been sworn into office, in accordance with Article II, Section I of the United States Constitution, by reciting the following affirmation:

"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."

I think it's safe to say that defending the U.S. Constitution is the President's primary responsibility, given that it's the only thing that he/she MUST EXPRESSLY AFFIRM in the Oath. This responsibility trumps any and all others.

You listening, Bush?
