Less than 33% of Puerto Rico supports statehood.

Based on what? In the referendum described here, two thirds of those who voted on the referendum answered the second question, and of those who answered the second question, 61% voted for statehood. So forty percent of those who voted on the referendum said they were in favor of statehood. That's more than the thirty three percent you claim. So you're not getting your thirty-three-percent number from the referendum. Where do you get it from?
