Has Obamacare's Medicaid expansion reached a tipping point?

Despite continued Republican efforts to repeal Obamacare, a key component of the law that has given millions of people health coverage — Medicaid expansion — could prove very difficult to undo, experts say. A growing number of states have signed up for that expansion of the government-run program for poor people, or are discussing doing so. Hospitals are becoming accustomed to the money that comes with expansion, and a majority of new enrollees are saying they are happy with their coverage. The difficulty of getting rid of Medicaid expansion, which uses federal dollars to give health benefits to previously ineligible adults, was sharply underscored this fall by the election of ardent Obamacare foe Matt Bevin as governor of Kentucky.
