Among the trademarks of the presidency of Barack Obama is his willingness to ignore the rule of law, and trample upon the dynamics of the American System. He is a dictator that is more than willing to go on his own to make sure his will be done. The Constitution is a mere obstacle to Mr. Obama, rather than the law of the land. He understands the Constitution, but he does not like it, so he circumvents the founding document at every opportunity.
Article I, Section 1 of the United States Constitution states that "all" legislative powers belong to Congress. The concept of "separation of powers" disallows the President from acting legislatively, since those authorities belong to Congress. Article II, Section 3 also tasks the President with "faithfully" executing the laws of the United States.
