Former Gov. Howard Dean, D-Vt., acknowledged that Obamacare increases the cost of health insurance for some people, but he argued that most Americans won't get "screwed" by the law.

Dean said that insurance would be cheaper, but "not for everybody," as he debated the American Enterprise Institute's Scott Gottlieb on the merits of the Affordable Care Act during "Fox News Sunday."

"Scott made a prediction here," Dean said. "I think he is partly right, but I think the numbers are going to be small enough so that the antis — the partisans are going to try to talk about all of these individuals who have gotten screwed by this. But most people, the vast majority of people are going to benefit from this."

Gottlieb, noting that "middle class folks really don't benefit [from] the subsidies" in the health care exchanges, predicted that their insurance costs would spike.

"Most of the people are people who had insurance are now being forcibly moved into the exchange and most of the middle class folks really don't benefit in the subsidies," he told Fox News' Chris Wallace. "They're going to find these plans much more expensive than what they were getting before."
