"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."

The italicized is the oath of office that is required by the US Constitution.

Ethics has to do with what is right and wrong, and not necessarily with what is legal.

Is it right to stand before the people and the highest judge in the land and swear that you will "preserve, protect, and defend the Constitution", when you've intentionally NOT abided by the spirit of that Constitution in regards to your qualifications for the office you have entered?

I say it's wrong: unethical.

I certainly agree that Obama is unethical; and he was lying when he took the oath because, far from "preserving and protecting," he is an aggressive domestic enemy of the Constitution. He has already taken numerous actions that are, IMO, sufficient grounds for impeachment. Having said that...

when you've intentionally NOT abided by the spirit of that Constitution in regards to your qualifications for the office you have entered?

I don't think that I could agree that Obama has not demonstrated his qualifications for the office. The short-form COLB seems adequate for that purpose to me.
