That's not entirely true; pro-status-quo groups have boycotted all or part of ballots, or advocated voting for some other option than continued territory status to avoid clear wins for Statehood. That was true in 2017 where they boycotted the whole ballot, in 2012 where they boycotted the second (alternative status) part of a two part ballotmarking that called for a vote up or down on current status and then a separate vote on what the replacement status should be; in 1998 where they called for a vote for “none of the above” so their votes would be added to genuine NOTA votes.

It's true that Commonwealth (territory) status won in 1967 and, narrowly, 1993, but it's clearly been declining over time, which is why that faction has been trying to deny clear results since 1998.

At least do some research.

The Democratic Party (well, it's currently dominant faction, at least) is also center right.

> If Puerto Rico were to join as a state you'd more likely than not find its politicians trying to retain their own party ties.

There'd be strong pressure to fuse with or be displaced by the national parties once PR was involved in Congress and, more importantly, Presidential elections; the days of states having distinct local major parties on a lasting basis likely ended when the Minnesota Farmer-Labor Party aligned with the national Democratic Party, and the nationalization (and globalization) of the media, combined with the way electoral politics works means that's unlikely to change even with the admission of new states with pre-existing party systems.

Besides that, it's really hard to believe that even Puerto Ricans with conservative views are going to break in significant numbers for a party that seems to be so hostile to them.

According to these sources it also beats South Korea, New Zealand, and Israel, which frankly surprised me a bit.
