In their fourth referendum on the subject since 1967, the citizens of Puerto Rico have for the first time selected statehood as their preferred relationship with the United States. (Puerto Rico is currently a territory of the United States.) In Tuesday's vote, two questions about Puerto Rico's status on the ballot. The first question, "Do you agree to maintain current territorial political status?" resulted in nearly 54% voting no. The second question as to what relationship Puerto Rico should have with the United States resulted in about 61% selecting statehood, 33% voting for "associated free state" (akin to Greenland's current status with Denmark), and a mere 5.5% selecting independence.
Statehood is not guaranteed for Puerto Rico as a bill must be initiated and pass the U.S. House of Representatives and U.S. Senate and then signed by the President of the United States. President Obama has previously suggested that he would, "respect the will of the people in the event of a clear majority." It is not known if a 54% vote is a clear majority that would result in Puerto Rico becoming the 51st state of the United States.
