Chamorro people
Guam has been occupied for over 450 years by the Spanish, the Japanese, and the United States. In 2016, Governor Eddie Calvo planned a decolonization referendum that the indigenous Chamorro people of Guam would solely participate in, in which the three options would be given, including statehood, independence, and free association. However, this referendum for the Chamorro people was struck down by a federal judge on the grounds of racial discrimination. In the wake of this ruling, Governor Calvo has suggested that two ballots be held: one for the Chamorro People and one for eligible U.S. citizens who are non-indigenous residents of Guam. A reunification referendum in Guam and its neighbor, the Northern Mariana Islands (a U.S. Commonwealth) has been proposed. A 2016 poll conducted by the University of Guam showed a majority supporting statehood when respondents were asked what political status they supported for Guam.
