“Before he enter the actual Execution of his Office, he shall take the following Oath or 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.” This is the oath of office that all Americans believe the President of the United States must uphold while executing his or her duties.
“To the best of my ability” are words that just about all of us can understand. On the positive side it means give it everything the individual possesses. It means give it his or her all. Further, it does not allow for one to slack off or shrug responsibility. So this is a very important obligation when it comes to protecting the constitution. It certainly would not allow for activity that is against the constitution.
What is the individual supposed to do to the “Best of their ability?” The words continue with the notion that the Constitution is to be preserved. Preserving the Constitution means keeping it basically the same, not spoiling it. Americans do not want the foundation of our country changed. This means that the President must perform actions that foster the preservation of the Constitution. There really should be little actions real or perceived to change it.
