Absolutely fascinating reading. Bound up in identity politics, but also shenanigans about how votes are counted, whats on the ballot, what combination of local politics vs the financial consequences for individuals (tax, benefits) you look at.

Puerto Rican's would gain some things in medicaid, have to pay different rates of tax, and lose some status in UN and LAC community contexts.

On the mainland, both major parties ostensibly support in principle self determination. That said, I don't see how the current political landscape could produce it, given the fracture lines.

I loved this footnote in the wiki page:

  Another misconception is that the import/export taxes collected by the U.S. on products manufactured in Puerto Rico are all returned to the Puerto Rico Treasury. This is not the case. Such import/export taxes are returned only for rum products, and even then the U.S. Treasury keeps a portion of those taxes
