Santorum: If Rubio is the Establishment, Conservatives Have Won

Santorum, the 2012 Iowa Caucus winner, defended Rubio against claims he is too establishment to be conservative.

"Ladies and gentleman, if he is the establishment, conservatives have won," he responded.

"I'm supporting Rubio for one reason: he is a conservative," Santorum said. "If you don’t believe me, believe the American Conservative Union. Because the ACU scores him a 98% rating. That is a conservative rating." 

"He is a conservative," Satorum continued. "He’s a winner. He can bring this country together."
