No, that can’t be right, because half the comments here say it’s due to racism.
Both those things are true, racists prevent it from becoming a state to prevent it from voting dem.
So if a Puerto Rican moves to a US state, they still can’t vote, right?
They can’t do this directly anymore, so they are just disenfranchised on Puerto Rico.
