You have to admire Barack Obama. He knows how to silence his competitors.
What to do with Hilary Clinton? Bring her well inside the tent to prevent any Johnsonian exterior-to-interior tinkling.
What to do with the person your main-man describes as "the only 2012 Presidential candidate who makes me worried" ? Simple. Send him to China for four years.
Mind you, Jon Huntsman, the Sino consignee in question does speak Mandarin (no mean feat), has a background in Eastern diplomacy and a Chinese adopted daughter. So once again, fortune is smiling on Obama....for the moment.
