Just a quick comment. Take a look at Europe, specifically Greece. State's rights advocates should be aware of the dangers of sovereign nations gathered in to a loose economic confederacy. The consequences can be devastating. We left our own confederation to make a more perfect union -- please note that unions are united. I agree with Franklin, "Thus I consent, Sir, to this Constitution because I expect no better, and because I am not sure, that it is not the best. The opinions I have had of its errors, I sacrifice to the public good."
