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.
Yes it is. There is another referendum on statehood this year, but in 2020, the vote was only marginally higher in favor of it than against.

That speaks volumes.
