The Arizona Constitution already says the federal Constitution "is the supreme law of the land." This measure, if approved in November, it would add language saying that federal document may not be violated by any government -- including the federal government.
More to the point, it would allow Arizonans "to reject any federal action that they determine violates the United States Constitution."
I want to see Sheriff Joe arrest some of the minions of darkness in flagrante delicto for trying to enforce an unconstitutional law.
