Rick Santorum On Mitt Romney: 'You Can Call Yourself A Socialist'

Rick Santorum is disputing Mitt Rommey's statement that Santorum is less conservative on economic issues.

"I didn't back Romneycare, which is a government takeover of one-sixth of the economy," Santorum told conservative radio host Mark Levin on Monday night, pointing to his own work with Ohio Gov. John Kasich (R) on health savings accounts during the Clinton administration.

"When Mitt Romney's solution to a healthcare problem is to take over one-sixth of the economy, you can't call yourself a conservative," Santorum said. "You can call yourself a socialist, but you can't call yourself a conservative."'

Earlier on Monday, Romney told FOX News, "Rick Santorum is not a person who is an economic conservative to my right. His record does not suggest he has the fiscal conservative chops that I have."
