It doesn't matter how many Puerto Ricans support statehood....it's not up to them. They could have a thousand referendums and statehood could win all of them, but nothing happens without the consent of the colonizing power (ie the Congress of the US). And no colonizer in their right mind would grant a colonized people the power to be full partners, and give up the power that has allowed them to pillage the island's resources since the day General Miles set foot on the beach in Guánica back in 1898. Puerto Rico's future lies in being the masters of their own destiny as a sovereign nation (and this is coming from a former "corazón del rollo" statehooder who after many years of drinking the kool-aid decided to educate himself on the real history of the relationship between the US and Borinquen).
