You might see large states donating 10 square miles to make a new state Just to get more senators to offset the new DC Senators Even a private owner of land could start a process for a new state with 10 square miles This is what happens when things are done for politics....
But not land mass. And it is obviously a political ploy to seize more power. If it was just about representation, you would be in favor of incorporating the areas back into Maryland.
Indeed.DC would stay DC with Congress redefining its borders as it did in 1846 and a new state would be made around it.
