Newt Gingrich’s rise to the top of the GOP polls is fueled, in part, by Republicans’ mistrust of Mitt Romney. Romney’s signature Massachusetts health-care law, the model for Obamacare, leads many to wonder whether Romney can challenge the president on this most important domestic issue. But any conservative who opposes Romney because of Romneycare should oppose Gingrich with thrice the intensity: Newt Gingrich is one of the principal abettors of the exploding health-care entitlement state we face today. Indeed, it’s not clear what would be worse for the cause of entitlement reform: Newt’s losing to Obama or Newt’s beating him.
