As commonwealth citizens, Puerto Ricans elect their own officials but they do not "vote in U.S. national elections".

Puerto Rico is a self-representing republic in relationship with the United States. Puerto Rico has authority over its inside issues. The real contrasts between Puerto Rico and the 50 states are exception from a few parts of the Internal Revenue Code, its absence of voting portrayal in either place of the U.S. Congress (Senate and House of Representatives), the ineligibility of Puerto Ricans dwelling on the island to vote in presidential races, and its absence of meeting of a few incomes held for the states. Puerto Rico has one resident commissioner (with voice, however no vote) in the Congress of United States. There are no appointive votes in favor of Puerto Rico in the U.S. presidential elections.
