Unlike Puerto Rico, you can arguably do DC through reconciliation depending on how cute you want to get with the Senate rules.
What is actually required to make both states?
I was under the impression that if voters in the district/territory voted in favor of statehood, and if a simple majority in the House and Senate agreed, that was all it took. What else has to happen?
(Apologies if I'm showing my stupidity.)
The Puerto Rico government which is currently anti-statehood has to draft a constitution and everything.
