A 2019 Gallup poll found 83% of Democrats in the US, but only 35% of Republicans, supported Puerto Rican statehood. A 2020 survey by International Policy Digest found that “The majority of Democrats showed support for statehood for both D.C. (61.8%) and Puerto Rico (69.7%)” while among Republicans, only 26.7% supported D.C. statehood and 34.8% supported Puerto Rican statehood.
That speaks volumes.
