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.

Internal self-government under a local constitution was authorized by Congress and approved by the residents in 1952, but federal law is supreme in Puerto Rico and residents do not have voting representation in the Congress.

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.

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 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.

After four centuries of Spanish rule, Puerto Rico was ceded to the United States in 1898. Residents were granted U.S. citizenship in 1917, and the federal government has allowed Puerto Rico to exercise authority over its local affairs in a manner similar to the 50 states.
