Barack Obama looked tired on Thursday, as he stood in the Blue House in Seoul, the official residence of the South Korean president. He also seemed irritable and even slightly forlorn. The CNN cameras had already been set up. But then Obama decided not to play along, and not to answer the question he had already been asked several times on his trip: what did he plan to take home with him? Instead, he simply said "thank you, guys," and disappeared. David Axelrod, senior advisor to the president, fielded the journalists' questions in the hallway of the Blue House instead, telling them that the public's expectations had been "too high."Uh, you think? I'm not going to say we (as in those of us who knew better) told you so. Actually, I changed my mind. WE TOLD YOU SO.
