Unrelated to the constitution.
Wrong. The Constitution requires the seat of the govt to be unattached to any single state. That is why they carved out the section from MD and VA as a district outside of state control. The seat of the govt cannot be its own state. Now, they can reduce the size of the district and allow the left over area to do something but the original agreement was if they did that the land in question would revert back to the original states. So people can find themselves residents of VA or MD rather than DC and that would not change the make up of the senate.
Granted the above requires the DEMs to adhere to the original agreement and we all know they won't do that.
