New Jersey is one of a handful of states with Republican governors that have expanded Medicaid under President Barack Obama’s signature health care law. Paul pointed to the number of Republican-controlled states that had not as evidence of Christie’s position.

“Many Republican governors I would say are conservative did resist expanding and accepting Obamacare in their states,” Paul said. “That fact, I would say, would lead towards you making the conclusion that it is not a very conservative proposal.”
