> The majority of supporting Puerto Ricans is quite slim (especially compared to the national support). A couple percentage points lower and the majority wouldn't be in favor.

So? Majorities are often slim. Just look at US elections. The difference is whether you have majority rule or minority rule.

> Although, if you're now switching to argue that the national opinion is _against_ (or at least the republicans would block it)

I'm not switching, I'm just saying it's a partisan issue, and Republicans happen to be over-represented in the national government due to territorial representation, which is how they're able to block Puerto Rican statehood, against the wishes of the majority. And it's pretty obvious why Republican leaders want to block Puerto Rican and D.C. statehood, because that would likely lead to additional Senate and House seats for Democrats.
