In 1967 Puerto Rico's Legislative Assembly polled the political preferences of the Puerto Rican electorate by passing a plebiscite act that provided for a vote on the status of Puerto Rico. This constituted the first plebiscite by the Legislature for a choice among three status options (commonwealth, statehood, and independence). In subsequent plebiscites organized by Puerto Rico held in 1993 and 1998 (without any formal commitment on the part of the U.S. government to honor the results), the current political status failed to receive majority support. In 1993, Commonwealth status won by a plurality of votes (48.6% versus 46.3% for statehood), while the "none of the above" option, which was the Popular Democratic Party-sponsored choice, won in 1998 with 50.3% of the votes (versus 46.5% for statehood). Disputes arose as to the definition of each of the ballot alternatives, and Commonwealth advocates, among others, reportedly urged a vote for "none of the above".
