1998 Puerto Rican status referendum
A referendum on the political status of Puerto Rico was held on December 13, 1998, five years after an inconclusive result in a 1993 status referendum.
Five alternatives were listed on the ballot: limited self-government, free association, statehood, sovereignty and none of the above. Disputes arose as to the definition of each of the ballot alternatives; and commonwealth advocates, among others, urged voters to vote for "none of the above", asserting that the commonwealth definition on the ballot "failed to recognize both the constitutional protections afforded to our U.S. citizenship and the fact that the relationship is based upon the mutual consent of Puerto Rico and the United States."
A slim majority of voters (50.5%) voted for the none of the above option.
