Obama has a repeated trope tonight, less irritating than McCain's: "I told you so." He did it with the Wall Street mess ("I wrote a letter warning Paulson...") and just now with the Georgia incursion.
He just changed topics to energy. Not a big stretch from Russia, but I don't think it was the assigned topic.
McCain took the bait. He just called offshorte drilling a "bridge." That was Paris Hilton's idea, remember? And he also opened up the problem with nuclear waste storage and reprocessing, which (as everybody knows) is the colossal unresolved problem with nuclear power.
