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.

Abdullah II bin Al-Hussein (Arabic: الملك عبد الله الثاني بن الحسين‎, al-Malik ʿAbdullāh aṯ-ṯānī bin al-Ḥusayn; born 30 January 1962) is the reigning King of the Hashemite Kingdom of Jordan.

Since 1993, Abdullah has been married to Queen Rania of Jordan.

Abdullah was born in Amman to King Hussein of Jordan during his marriage to British born Princess Muna al-Hussein. He was the king's oldest son and as such he was automatically heir apparent to the throne of Jordan under the 1952 constitution. However, due to unstable times in the 1960s, King Hussein decided to appoint his brother, Prince Hassan bin Talal, as his heir.

King Abdullah II attended St Edmund's School, Hindhead, Surrey, before moving on to Deerfield Academy in Deerfield, Massachusetts. He joined the Royal Military Academy Sandhurst in 1980, was commissioned as a Second Lieutenant, and served as a troop commander in the 13th/18th Royal Hussars.

Walsh School of Foreign Service at Georgetown University in Washington, D.C. Abdullah would later serve in the Jordanian forces and became Major General in May 1998.
