June is the month for major decisions from the US Supreme Court, and no case is being watched more closely by more people than King v. Burwell. At stake is continuation of the Affordable Care Act. And it all comes down to four little words. The Court may give Republicans what they've been demanding: a ruling that strikes at the heart of Obamacare. But the GOP can't agree on what to do when millions of Americans lose subsides for health insurance and the industry is thrown into chaos. There's no contingency plan from the Obama White House either, and politicians of both parties are worried about taking the blame in next year's elections. Possible options include an end to individual and corporate mandates — along with coverage for pre-existing conditions.
