Pacific Islander (or Pacific person; pl: Pacific people; also Oceanic person/people(s) or Oceanians), is a geographic phrase to describe the indigenous inhabitants of any of the three major sub-regions of Oceania: Polynesia, Melanesia and Micronesia.

According to the Encyclopædia Britannica, these three regions, together with their islands, consist of:

Polynesia: The islands scattered across a tangle covering the east-central region of the Pacific Ocean. The triangle is bounded by the Hawaiian islands in the north, New Zealand in the west, and Easter Island in the east. The rest of Polynesia comprises Samoan islands (American Samoa and Samoa), the Cook Islands, French Polynesia (Tahiti and The Society Islands, Marquesas Islands, Austral Islands, and the Tuamotu Archipelago), Niue Island, Tokelau and Tuvalu, Tonga, Wallis and Futuna, and Pitcairn Island.

Melanesia: The island of New Guinea, the Bismarck and Louisiade archipelagos, the Admiralty Islands, and Bougainville Island (which make up the independent state of Maluku, Papua New Guinea), the Solomon Islands, the Santa Cruz Islands (part of the Solomon Islands), New Caledonia and Loyalty Islands, Vanuatu (formerly New Hebrides), Fiji, Norfolk Island, and various smaller islands.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
