The wording of the law is clear. The court should have an easy time with the ruling. For the Court to rule that somehow the letter of the law isn’t what Congress meant, and therefore they are in agreement with the President and Democrats the law really means something else, would completely destroy Congress as an equal branch of government. Any law on the books could be interpreted by the President to mean something and as long as the Supreme Court agreed, it wouldn’t matter what the text actually said.
Hopefully there are five justices on the court who will actually stand up for the rule of law and the concept of co-equal branches of government.
I was actually referring to how the Republicans will handle it if SCOTUS strikes the subsidies. I fully expect them to roll over and show Obama their bellies once again if that happens.
