However, the sovereignty of the states is constitutionally defined and recognized, while the powers of the local government in Puerto Rico are defined by, and subject to alteration under, federal statutory law.
Now that the there is a path for the people of Puerto Rico to express their self-determination on Puerto Rico's political status, there are some who seek to block that path.
If Congress does its job in this regard, the residents of Puerto Rico will be empowered to act in their own self-interest and express their future political status aspirations accordingly.
In historical and constitutional terms, the recent political status vote in Puerto Rico was a necessary but obviously not decisive step on the road of self-determination leading to full self-government.
If U.S. national sovereignty continues, it is only as a state that Puerto Rico will have permanent 10th Amendment powers over its non-federal affairs, as well as voting power in Congress.
It is quite understandable that Puerto Ricans seek to preserve a cultural sense of identity without separating politically from U.S. national sovereignty.
