The Eastern District Court of Oklahoma ruled to strike down Obamacare's subsides on federal exchanges, consistent with a ruling in a related lawsuit earlier in the summer. The question at the center of these lawsuits is whether the text of the Affordable Care Act authorized subsidies — financial assistance offered to some people to help purchase health insurance — on all insurance exchanges, or only in those states that set up their own. In Obamacare's first year, 14 states and DC set up exchanges; the others defaulted to the federally-run Healthcare.gov. Without subsidies, private insurance would become unaffordable for many people who have already enrolled.
