The Affordable Care Act mandates that all Americans get health coverage or pay a penalty. To help people pay for that insurance, the federal government subsidizes insurance premiums for millions of Americans.
In just a couple of months, the Supreme Court will rule in a major case concerning those subsidies. The question is whether the law allowed for them across the country or just in the minority of states that set up their own insurance exchanges. A decision to take away those subsidies could leave millions without insurance.
