George Washington in his farewell address wisely foresaw how enemies, both internal and external, would attempt to break up the nation. In 2011, the Koch brothers and the Tea Party Congress attempted to use the states' rights issue to do just that It was called the Repeal Amendment.
Under this proposed amendment, supporters aimed “to push back the federal government's encroachment on sovereign states rights."
In effect, it would invalidate the “united” part of the “United States” since state legislatures would have final say-so on the law of the land. The United States would, therefore, become about as united as say, the United Nations.
The states’ rights issue has long been a contentious one. It was used to form the basis of the South secession before the Civil War. But the debate goes back even further, to the very creation of the United States and before the creation of the Constitution.
