+5 Yes, Puerto Rico is widely considered a colony—or often described as the world’s oldest colony—due to its status as an unincorporated U.S. territory. While residents are U.S. citizens, they lack voting representation in Congress, cannot vote for president,

From what I’ve heard there isn’t really a consensus among Puerto Ricans on what they want their status to be.
People indigenous to the island are very split between moving to closer alignment with the US via statehood or to move toward independence and ending the colonial commonwealth system. The only true consensus is that the current status quo is unsustainable and something needs to change.
Correct. The last vote barely failed. Think it was 51/49 or something close to that.
