Facing a possible Supreme Court ruling on Obamacare that could cost residents millions of dollars in subsidies to buy health insurance, Delaware has put in motion a plan that could protect the state from the effects of such a decision.

Rita Landgraf, Delaware’s health and social services director, confirmed to TPM Wednesday that the state has filed a “blueprint” to the federal government to take more responsibility for its Obamacare exchange to blunt the potential effects of a pending Supreme Court ruling in King v. Burwell.
