At the Des Moines Register Democratic debate Hillary and Obama went at each other over Obama's use of Clinton advisors:
Across 90 minutes, the fierce competition between the two Iowa front-runners shone through only once when Obama was asked how he could offer a new type of foreign policy since several of his advisers once worked for President Clinton.
Hillary Clinton laughed out loud at that, and said with a smile, "I'm looking forward to hearing that."
Obama, also smiling, waited for the laughter to die down before saying, "Hillary, I'm looking forward to you advising me as well."
Score one for Obama. He who laughs last . . . .
