The citizens of Puerto Rico are overwhelming apathetic with regard to statehood. In the 2017 referendum, only 23% of registered voters participated. The pro-status-quo group boycotted the referendum, and 500,000 blank ballots were later discovered. A completely dysfunctional and corrupt territorial government there.
On March 22, 1873, the Spanish National Assembly finally abolished slavery in Puerto Rico. The owners were compensated with 35 million pesetas per slave, and slaves were required to continue working for three more years. Long after the US had!
