"...can he actually take the oath of office of the presidency, and swear to uphold and defend the Constitution without perjuring himself?"
Nathan doesn't go far enough though. Here's the oath (with my own emphasis):
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.From what I've heard and read Obama is planning on enacting Constitution 2.0 instead.
Regardless, Clinton proved that presidents get a pass on perjury. So it looks like voters are on deck for the preserving, protecting and defending. I don't even want to consider who/what is next in the lineup.
