 When we say that Congress has powers, and we say that Congress can do everything that's necessary and proper to carry out those powers, what do we mean by that? And they keep emphasizing over and again, well, it's the powers to accomplish that which needs to be accomplished in order to run the government. It's the big ideas, I think, in the Federalist Papers. And whether or not you cite them in a particular case doesn't mean that the big ideas aren't still very important in the overall operation of the Court.
