One of the most beautiful moments of last night in St. Paul was after Obama's speech, after he had done the rope tour and was heading out of the arena proper. An Obama-of-tomorrow boy -- seven or eight? -- was hanging over the railing right by the door. Obama saw him, stopped, reached up, and rubbed his head in rough man/boy affection style. And then... Obama cradled one side of he boy's face in his hand, tenderly, for a long time.  It was not for show. It was just Obama, still able to be moved. And a boy, who will never forget that moment. Not captured in still photos, but there are some photos that show the boy right before OBama noticed him.Yes We Can.
