DC residents seek Statehood because it is the most appropriate mechanism to grant the US citizens who reside in the District of Columbia the full rights privilege of American citizenship. These rights would include not only full voting rights in the US House of Representatives and US Senate, but also full control over its own local affairs.
The United States is the only nation in the world with a representative, democratic constitution that denies voting representation in the national legislature to the citizens of the capital.
DC elects a Delegate to the House of Representatives who can vote in committee and draft legislation, but does not have full voting rights. However, Congress is considering legislation that will grant DC's Delegate full voting rights. They must act now!
