Puerto Rican citizenship
In 1952, upon U.S. Congress approving the Constitution of the Commonwealth of Puerto Rico, also reaffirmed that Puerto Rican citizenship continued in full force. This was further reaffirmed in 2006 while the U.S. Senate probed into the President's Task Force on Puerto Rico's status. In 1953, U.S Ambassador Henry Cabot Lodge Jr., in a memorandum sent to the United Nations, recognized that "the people of Puerto Rico continue to be citizens of the United States as well as of Puerto Rico."
Puerto Ricans
Puerto Ricans and other U.S. citizens residing in Puerto Rico cannot vote in presidential elections as that is a right reserved by the U.S. Constitution to admitted states and the District of Columbia through the Electoral College system. Nevertheless, both the Democratic Party and Republican Party, while not fielding candidates for public office in Puerto Rico, provide the islands with state-sized voting delegations at their presidential nominating conventions. Delegate selection processes frequently have resulted in presidential primaries being held in Puerto Rico. U.S. Citizens residing in Puerto Rico do not elect U.S. Representatives or Senators, however, Puerto Rico is represented in the House of Representatives by an elected representative commonly known as the Resident Commissioner, who has the same duties and obligations as a representative, with the exception of being able to cast votes on the final disposition of legislation on the House floor. The Resident Commissioner is elected by Puerto Ricans to a four-year term and does serve on congressional committee. Puerto Ricans residing in the U.S. states have all rights and privileges of other U.S. citizens living in the states.
