I agree for the historical reasons, but I don't think it should be left to Puerto Rico if they can't decide. The US should just say we are (state-hooding/evicting) you, unless you decide one way or the other. Along those same lines, I also think DC should gain representation in congress in some manner, either by largely becoming part of VA, or by becoming a 51st state(DC has more people than Wyoming or Vermont, and about as much as Alaska).
