You mean the 5 plebiscites out of which only the first from over 60 years ago favored remaining a territory? Those plebiscites only provide wiggle room because of issues with which and how many options were presented.

Officially, both political parties tend to say they support self determination for Puerto Rico, but still nothing has happened.
