Opponents of ending taxation without representation for the majority-minority District of Columbia argue that the District is too small (pop 700k) to deserve two votes in the U.S. Senate.
This criticism is, of course, absolutely right, and not in any way racist or related to maintaining an undemocratic minority hegemony in Congress.
Therefore, I propose adding the District to the State of Wyoming (pop 580k), thereby fixing this problem in two places at once.
Congress drew the present boundaries of Wyoming in 1890, and would only need to amend its Act to Provide for the Admission of the State of Wyoming into the Union to effect this change.
I am unaware of any provision of law requiring that states comprise contiguous territories, but if need be Congress could also transfer to Wyoming land area an inch wide along the present boundaries of Virginia, Tennessee, Kentucky, Missouri, and Nebraska, to connect the two areas.
(And wouldn’t Eldredge Gerry be proud!)
As a sovereign state, of course, the redrawn Wyoming would be free to relocate its capitol city east, to be closer to the majority of its residents.
I suppose it is possible that a change of this magnitude might ruffle some feathers, even though it rectifies the population problem that is the sincere and principled concern of the foes of DC statehood.
An acceptable compromise might be to permit separate statehood for the District, plus the end of the Electoral College or the creation of additional Senate seats for large states. But that, of course, would require a constitutional amendment and ratification by the states.
