At least two Republican presidential candidates at Tuesday night's foreign policy debate agreed that the Transportation Security Administration could do a better job if they began profiling Muslims.

CNN's Wolf Blitzer noted that former Pennsylvania Sen. Rick Santorum had advocated profiling in the past.

"Just to be precise, is it ethnic profiling, religious profiling, who would be profiled?" Blitzer asked.

"The folks that are most likely to be committing these crimes," Santorum replied. "Obviously Muslims would be someone you'd look at, absolutely."

"That's digging our hole for ourselves," Rep. Ron Paul disagreed. "What if they look like [Oklahoma City bomber] Timothy McVeigh."

Businessman Herman Cain told Blitzer that he agreed with Santorum.

"I call it targeted identification," Cain explained.

"What does that mean?" Blitzer asked.

"Targeted identification," Cain replied. "If you take a look at the people who have tried to kill us, it would be easier to figure out exactly what that identification profile looked like."

"It it OK for Muslim Americans to get more intensive pat downs or security when they go through airports than for Christian Americans or Jewish Americans?" Blitzer pressed.

"No, Blitz. That's oversimplifying it," Cain replied. "I'm sorry, Blitz. I meant Wolf."
