Medicaid expansion should have been for all fifty states.  However due to a Supreme Court ruling that hobbled Medicaid expansion that made it contingent on the whim of the governor of a state.  So the actual number of people who would have been covered by Medicaid expansion and paid at 100% of coverage by the federal government would have been many more people.  What would have happened is that medical caused bankruptcies would have decreased even further and the newly covered would have had access to preventative medical services.  Further down the road those people would enter into Medicare healthier which would translate into much more savings from a reduced use of services.
