U.S. state
States divide their territory into counties, or something similar with different name, which are not sovereign.  Most states give their counties some government authority; a few states give them none. State governments get their power from the people of that state.  States have a number of States' rights under the United States Constitution.  States and the people that live in them are represented in the United States Congress, in the Senate and the House of Representatives.  Each state also selects electors (an equal number to the number of Senators and Representatives from that state) to vote in the Electoral College, which elects the President of the United States. Puerto Rico, a territory of the United States, is considered as a possible 51st state for the future.
