If the Supreme Court later this month strikes down Obamacare subsidies in states with federal insurance exchanges, the narrative is simple: The health care law could be fatally crippled and marketplaces will fall into 34 simultaneous death spirals.

But what if Obamacare’s conservative challengers lose King v. Burwell?

If that question seems less sexy in a policy sense, that’s because it is. Essentially, if the Court decides the federal government is on the right side of the law, nothing happens; business continues as usual in all 50 states’ Obamacare exchanges. People keep their insurance as is.

But politically, an Obama administration win would mean volumes.
