George Ashford had this article in Fair Vote:
Last month, U.S. Senator Bob Menendez (D-N.J.), U.S. Representatives Nydia M. Velázquez (D-N.Y.) and Alexandria Ocasio-Cortez (D-N.Y.), introduced the Puerto Rico Self-Determination Act of 2021 — a piece of legislation that would empower Puerto Ricans with an inclusive and democratic process to determine their own political future and relationship with the United States.
The United States has maintained a form of colonial governance over Puerto Rico for well over 100 years. Neither independent nor a full-fledged part of the U.S., the island’s future has been long-debated, and recent political and economic crises have fueled calls for a change to its status.
Congress isn’t settled on the best way to structure Puerto Rico’s self-determination process. A bill that was introduced by Congressman Darren Soto (D-FL) and Puerto Rico’s sole representative in Congress, Jenniffer González Colón (R-PR), would admit Puerto Rico as a state, if ratified in a yes/no referendum by the people of Puerto Rico.
