DC Statehood has been in the news recently, and I'm wondering about the logistics of it. First, take this excerpt from Article IV Section 3 of the Constitution:
New states may be admitted by the Congress into this union; but no new states shall be formed or erected within the jurisdiction of any other state; nor any state be formed by the junction of two or more states, or parts of states, without the consent of the legislatures of the states concerned as well as of the Congress.
Although I would imagine DC is not considered to be under the jurisdiction of Maryland or Virginia, it seems to be at the junction of the two states, right? Also, how would we define "part?" Is DC a "part" of Maryland? So would DC statehood technically require approval from the Maryland and Virginia state legislatures?
Now, here's an excerpt from Article I Section 8
The Congress shall have Power To… exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States…
Giving Congress the power to "exercise exclusive Legislation in all Cases whatshoever, over such District" seems pretty mutually exclusive with statehood. Would the Constitution need to be amended for DC statehood?
