On September 11, Bruce Ackerman, a Yale professor of law and political science, had an opinion piece published in the New York Times fittingly titled "Obama Betrays the Constitution". 

Ackerman describes how Obama has broken with the "tradition" of presidents abiding by the Constitution as well as betraying the majority of Americans who twice elected him to the highest office in the land. But why are we surprised at his "betrayal" and break with with "tradition"?

This is the logical conclusion of Progressivism that began almost exactly 100 years ago with Woodrow Wilson becoming the first "progressive" Democratic president to decide that he was going to unilaterally redefine what rights meant under the Constitution, from negative rights (generically meaning freedom from interference) to positive right (i.e., the gov't decides what's in the best interest of everyone and legislates that "right" into law) 

The watershed events were FDR's New Deal and LBJ's Great Society, which created behemoth federal bureaucracies in the name of providing those "rights" for Americans. Obama has taken federal power as defined by Wilson, FDR, LBJ, and Progressivism to its logical conclusion by asserting executive actions and war powers without the consent of congress because in his words, if congress is not going to act, "I have to do what's right for the American people'.

Finally, it is not surprising that Obama has betrayed his two electoral majorities. He came into office portraying himself as a centrist in disguise but slowly the mask has been falling away and the genuine Alynskyite that he is has been revealed for all to see at last. Power and only power has been the end-game all along.
