Puerto Rico has had five previous referendums on its status. A vote in 1967 rejected statehood, with the commonwealth status option receiving the most votes. The next three referendums produced no clear majorities, with the commonwealth option receiving the most votes in 1993 and the none of the above option being the most popular option in 1998. The two-party referendum in 2012 saw a majority vote in favour of a change in the status quo and for statehood, but he way the ballot was introduced created doubt in Congress. A non-binding 2017 referendum was in favor of statehood, but had only a 23% turnout.
