The short answer is nothing. The document is the framework of our government. Powers among the three branches are clearly enumerated. Article II – Section 1 prescribes the oath of the office for the President of the United States as follows:
“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.”
So how then can President Obama, who took that oath twice, completely ignore it? As late as October 2013 he acknowledged that as President he has no power to act on his own to create law, that he can only enforce the law.
Yet last Thursday that is exactly what he did when he announced his executive order on illegal immigration (or was that “Undocumented” immigration).
Article II gives the President no right to create laws, he must enforce the law as enacted by Congress as described in Article I. His action last week was a creation of law and as such was a direct violation of the Constitution.
What is wrong with the Constitution? Nothing.
The real question is: What is wrong with this President?
