The United States Congress has ultimate authority over the District.
The District is not a U.S. state and therefore has no voting representation in the Congress. D.C. residents elect a non-voting delegate to the House of Representatives, currently Eleanor Holmes Norton (D-D.C. At-Large), who may sit on committees, participate in debate, and introduce legislation, but cannot vote on the House floor. The District has no official representation in the United States Senate. Neither chamber seats the District's elected "shadow" representative or senators. Unlike residents of U.S. territories such as Puerto Rico or Guam, which also have non-voting delegates, D.C. residents are subject to all U.S. federal taxes.[176] In the financial year 2012, D.C. residents and businesses paid $20.7 billion in federal taxes; more than the taxes collected from 19 states and the highest federal taxes per capita.[177] A 2005 poll found that 78% of Americans did not know that residents of the District of Columbia have less representation in Congress than residents of the 50 states.[178] Efforts to raise awareness about the issue have included campaigns bygrassroots organizations and featuring the city's unofficial motto, "Taxation Without Representation", on D.C. vehicle license plates.[179] There is evidence of nationwide approval for D.C. voting rights; various polls indicate that 61 to 82% of Americans believe that D.C. should have voting representation in Congress.[178][180] Despite public support, attempts to grant the District voting representation, including theD.C. statehood movement and the proposed District of Columbia Voting Rights Amendment, have been unsuccessful.
Opponents of D.C. voting rights propose that the Founding Fathers never intended for District residents to have a vote in Congress since the Constitution makes clear that representation must come from the states. Those opposed to making D.C. a state claim that such a move would destroy the notion of a separate national capital and that statehood would unfairly grant Senate representation to a single city.[181]
