Robert’s failure to comply with his oath of office can theoretically become grounds for his future impeachment, if and when true conservatives gained control of the Congress.
Until then, it remains to be seen how much longer these officers of the government can act in contempt of the letteer of the Constitution.
My theory is that when 0bama was making the rounds back in ‘08 he admitted to SCOTUS and certain members of congress that he was in fact a bastard, and had no idea who his father really is. The fake BC, IDs, etc. are a way for him to save face and they know it and cover for him.
It's an ancient problem. "Who shall guard the guards?"
