Mr. Obama hasn't changed more than would be expected over several years and, while I can't speak with certainty, I would be very surprised to find out that he was lying about his views during the presidential campaign (I don't know about his promises).

He has more information than he did then. And he trusts himself to use these powers more than he did the Bush administration.

Even postulating some revolutionary secret information seems to me to be unnecessary.

Obama has always trusted himself. Most people do. What's changed is that the president is now someone who is trusted by Obama. Everything that's happened up to this point falls nicely out of those circumstances.
