Huntsman hits Perry on foreign policy, focuses efforts on New Hampshire

"Unprecedented. I've never seen it before, I've never heard of it before, and I thought it was bad practice," Huntsman said.

The former Utah governor said that while he had disagreements with Perry, he was more concerned with building his campaign's momentum than reacting to the flavor-of-the-month leading the Republican field.

"You want to be a rising star, you don't want to be a shooting star," Huntsman said.

He also reiterated that the campaign would be pinning its hopes on New Hampshire. Huntsman is polling in the low teens in the state — his best showing by far — but still substantively trails former Massachusetts Gov. Mitt Romney.

"It's going to get very competitive," Huntsman said. "This is a state where the voting population has seen it all, heard it all."

Still, Huntsman said that the focus of his campaign would pay dividends — and represented a strategy that was affordable and realistic. Huntsman said he didn't anticipate writing another check to his campaign, and was working to woo on-the-fence conservative voters.

"Money is going to follow the message," Huntsman said. "We're doing about what I expected."
