Herman Cain's 9-9-9 Plan Takes Center Stage, and Potshots

As he rises in the polls, Herman Cain got more critical attention from his rivals at the debate table in New Hampshire on Tuesday night.

Following Jon Huntsman's jab about Cain's "9-9-9" tax plan sounding like a pizza offer, Rick Santorum asked the Dartmouth College audience for a show of hands supporting Cain's proposed national sales tax.

"That just gives Nancy Pelosi a new [tax] pipeline," Santorum said.

Cain volleyed back at the former Pennsylvania senator's contention that 9-9-9 cannot pass, saying, "Politicians want to pass what they think can get passed, rather than what we need. People want solutions, not just kicking the can down the road."
