Has the U.S. Supreme Court construed the commerce clause so permissively that Congress has seized, by increments, a sweeping police power that enables it to do virtually anything it wants?
Yes. Duh! How hard is this to understand?? How many more such essays are conservative and libertarian pundits going to write? Blah blah blah "10th Amendment!!" blah blah blah "Founders' Intent!!" blah blah blah "Federalism!!" It's like a bunch of people sitting around a burnt-out light bulb endlessly talking about how illuminating and warm it was. It's burnt out!
Perhaps I'm being too harsh. Go on quoting Marbury vs Madison, George. I'll go on living 200 years later, in what is often referred to as "the real world."
