Puerto Rico has been a part of the United States for over a century, and yet its people are still denied many of the rights of full citizens because it is a commonwealth of the US instead of a full state. Puerto Ricans overwhelmingly want to be a state, and we should endorse this and make it happen.
"Puerto Rico should be a state - they function as one right now without the political rights and bankruptcy protection. If Puerto Ricans looked like Swedes they’d be a state already. We must not only offer them political equality but help them rebuild their economy and infrastructure - it will take time but that’s what Americans do."
