Puerto Rico periodically holds plebiscites to determine the will of the people as to the status of the island. They can choose independence, statehood, or remain as is. Every time the people choose to keep the status as it is.
Independence, when I was there in the 60’s, came in around 0.1%. Statehood, favored by the PR Republicans, came in second, well behind the “as is.”
The last time they held one of those plebiscites I believe the three options were almost tied. They each came out between 30 and 40%. I might be wrong though.
