Last week, President Barrack Obama appeared on The Tonight Show to make us laugh over issues like the financial crisis, the burgeoning deficit, the energy crisis, the dubious future of American prosperity and, of course, to give us the latest gossip on the impending presidential dog.

(Laughter and applause … )

Obama wasn’t an ordinary late night TV guest. First, he is the sitting President of the United States — the first to ever appear on late-night TV. Second, he wasn’t there to promote a new movie, TV show or book. Rather, as soon became apparent, he was there to promote the economic agenda of his administration.
