Obama plans to bring home next month the first batch of about 100,000 American servicemen currently in Afghanistan, with all combat troops leaving by 2014.

Huntsman, a former Utah governor who was Obama's ambassador to China, thinks that may not be fast enough because of the financial cost of the war and because of waning public support.

“When you look at Afghanistan, can we hang out until 2014 and beyond?” Huntsman asked. “You can, if you're willing to pay another quarter of a trillion dollars to do so.”

Huntsman tells CNN's “State of the Union” that it's his “hunch” that Americans want to be “out of there are quickly as we can get it done.”
