This is unconstitutional, the District of Columbia is not a state. To amend the Constitution, it must pass a 2/3 approval in both the House and Senate and be ratified by 3/4 of the legislatures of the 50 states.
A constitutional amendment was drawn up on this very subject in 1978, to give the District of Columbia congressional representation. It was ratified by far less than the 38 states required. It was passed by 2/3 of each house of Congress, but not enough states ratified it.
This is absurd. Back in 1978, people realized and accepted that a constitutional amendment was needed to accomplish what they are trying to do. But now, in 2009, the Obamaniacs figure that their Dem. majorities in Congress are enough.
How can this be? If it required an amendment in 1978, it still requires an amendment now, because the legal status of D.C. has not changed since then.
