Jonathan Cohn: “A new estimate from the Kaiser Family Foundation suggests that, if fully implemented, the House Republican budget would reduce Medicaid enrollment nationally by between 14 million and 27 million people. (Kaiser Health News is an editorially independent program of the Foundation.) That’s above and beyond the 17 million who would not get Medicaid because the Republicans would also repeal the health law. And while conventional wisdom suggests Republicans will not succeed fully in either endeavor, the latest signs from Washington suggest the Republicans could very easily extract significant Medicaid reductions before the budget negotiations are over.”
