The Senate’s Obamacare repeal bill may protect Alaska and up to four other sparsely populated states from major cuts to Medicaid through 2026, a potential boon to the home of pivotal GOP swing vote Sen. Lisa Murkowski.The plan from Lindsey Graham (R-S.C.) and Bill Cassidy (R-La.) allows a limited number of states to opt out of its new Medicaid financing system, which would give states set sums to run their programs and do away with the open-ended entitlement that exists today.Murkowski helped kill the GOP’s “skinny” repeal bill in July and is being heavily courted by Republicans to support the latest repeal effort.
