“nearly a decade after the Supreme Court ruled that states could choose whether to expand their Medicaid programs, the fight over whether to do so is far from over. So far, 38 states and Washington, DC, have expanded Medicaid, covering nearly 15 million people. In the dozen states that have not, 4 million people are uninsured who would receive Medicaid coverage if their state expanded eligibility under the ACA. More than 95 percent live in the South, they are disproportionately Black, and many are not eligible for subsidies to buy private coverage on the ACA markets.”
