WASHINGTON (AP) — The Supreme Court argument over subsidies that help millions of people afford their health insurance suggests that the Obama administration has two chances to attract one critical vote.

The justices will gather in private Friday to cast their votes in the case. The outcome after Wednesday's argument appears to be in the hands of two conservative justices. Chief Justice John Roberts voted with the court's four liberals to uphold the law in 2012. Justice Anthony Kennedy joins the liberals more often, but would have killed the whole thing three years ago.

But on Wednesday, Kennedy at least left open the possibility that he would not vote the same way again because of a legal concept known as constitutional avoidance.
