Puerto Ricans have continually voted down statehood. Right now they get the best of both worlds (no Federal taxes, but Federal subsidies, food stamps, welfare, US Citizenship, etc.)
Why would they ever want to end the free ride?
English or no, getting them to start paying Federal taxes would actually represent progress.
It’s why I never understood the Puerto Rican terrorists who wanted independence. I know of no American who would oppose giving them their independence if they wanted it.
I'm thinking 2 Senators from PR would not represent progress.
