Sen. John Thune (R-S.D.) tweeted this on Monday.

To an outside observer who may not be terribly familiar with Obamacare (née the Affordable Care Act), this seems alarming. Whoa, Obamacare may cost people their health-care subsidies? such observers may think. And the answer is, haha, well, sort of.

The subsidies that might be lost if the Supreme Court rules against the Obama administration in the case of King v. Burwell are subsidies ... that exist within the framework of Obamacare. Obamacare isn't threatening those subsidies, Obamacare is providing them. The threat to the subsidies lies with the Supreme Court case, which could interpret language within the law to exclude people who signed up through HealthCare.gov from access to those subsidies. Millions of people in states using the federal Obamacare exchange could lose subsidization of their coverage -- but they only got those subsidies and that coverage through the exchange! And several of Thune's Senate colleagues filed an amicus brief supporting rejection of the subsidies.

Thune's argument is akin to saying that the free car you won on "The Price is Right" is a bad car because his buddies stole the engine. There are lots of valid critiques of Obamacare. That people who have enrolled in health insurance might lose subsidization of those plans because of how the Supreme Court interprets one sentence is not one of them.
