Governments
Consequently, each of the 50 states reserves the right to organize its individual government in any way (within the broad parameters set by the U.S. Constitution and the Republican Guarantee enforced by Congress) deemed appropriate by its people, and to exercise all powers of government not delegated to the federal government by the Constitution. A state, unlike the federal government, has un-enumerated police power, that is, the right to generally make all necessary laws for the welfare of its people. As a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance. No two state governments are identical.
