House Republicans are planning to cut roughly $1 trillion over 10 years from Medicaid, the government health insurance program for the poor and disabled, as part of their fiscal 2012 budget, which they will unveil early next month, according to several GOP sources. Though Budget Committee Chairman Paul Ryan has yet to lock in his final numbers, he made clear to POLITICO in February that he intends to target Medicaid and Medicare for savings. While Medicaid is easiest to win consensus on, Medicare is the biggest debt driver. It’s not yet clear how much Ryan hopes to cut from Medicare, and he and GOP leaders have been reluctant to discuss their plans for the other entitlement behemoth: Social Security. But they’ve made clear that they don’t consider Social Security to be as pressing an issue as Medicare and Medicaid.
