The title does not do justice to the content of the article. The author is explaining how the group behind the push for a COS is wrong, and explains why he thinks so. He ends with this: > So, in light of that possibility, there is no need to try to address the issues plaguing our country by putting the Constitution in harm’s way. There is another remedy, a “rightful remedy” as Thomas Jefferson called it: state interposition. > Here’s how Jefferson’s best friend and writing partner, James Madison, explained why and how the states could prevent — how the states were obliged to prevent — unconstitutional acts of the federal government from being enforced: >> This Assembly … views the powers of the federal government, as resulting from the compact, to which the states are parties; as limited by the plain sense and intention of the instrument constituting the compact; as no further valid that they are authorized by the grants enumerated in that compact; and that in case of a deliberate, palpable, and dangerous exercise of other powers, not granted by the said compact, the states who are parties thereto, have the right, and are in duty bound, to interpose for arresting the progress of the evil, and for maintaining within their respective limits, the authorities, rights and liberties appertaining to them. > Simple. States created the federal government, and the federal government has no authority beyond that granted to it by the states in the Constitution. Any act of the federal government that exceeds that authority is to be prevented from being enforced by the states, who “interpose,” that is to say, prevent the unconstitutional act from being enforced. The states not only have the right to do this; they have the duty, Madison says, to do this.
