The governors of 15 Republican-leaning states have signaled that they will not participate in the Affordable Care Act’s Medicaid expansion, a new analysis finds.

The Supreme Court’s ruling on the Affordable Care Act gives states the choice of opting in or out of the law’s massive expansion of Medicaid — the state-federal program that funds a vast majority of nursing home care. If states choose to participate, the Medicaid expansion would extend health insurance to uninsured adults with incomes below 138% of the federal poverty level.

Although the federal government has said it will pay the cost of the expansion from 2014 to 2017, and then 90% of the costs afterward, that leaves states picking up about 7% between 2014 and 2022, the Congressional Budget Office said. The group of governors said they would refuse $931 billion in federal funds during that time period.

The expansion’s detractors include Texas Gov. Rick Perry (R), Florida Gov. Rick Scott (R) and Louisiana Gov. Bobby Jindal (R) among others, according to The Hill’s analysis. They argue that their states are already struggling to support existing Medicaid rolls.
