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.

Martin Wolf, CBE (born 1946) is a British journalist, widely considered to be one of the world's most influential writers on economics. He is the associate editor and chief economics commentator at the Financial Times.

Wolf was born in London, 1946. His father Edmund was an Austrian Jewish playwright who escaped from Vienna to England before World War II. In London, Edmund met Wolf's mother, a Dutch Jew who had lost nearly thirty close relatives in the Holocaust. Wolf recalls that his background left him wary of political extremes and encouraged his interest in economics, as he felt economic policy mistakes were one of the root causes of WWII. Wolf was educated at University College School and in 1967 entered Corpus Christi College at Oxford University for his undergraduate studies. He initially studied Classics before starting the Philosophy, Politics and Economics Course As a graduate student Wolf moved on to Nuffield College, also at Oxford, which he left with a master of philosophy degree in economics in 1971. Wolf has said that he never pursued a PhD because he "didn't want to become an academic". Wolf was an active supporter of the Labour Party (UK) until the early 1970s.

Abdullah Gül (Turkish: [abduɫˈɫɑh ˈɟyl]; born 29 October 1950) is the 11th and current President of the Republic of Turkey, serving in that office since 28 August 2007. He previously served for four months as Prime Minister from 2002-03, and as Minister of Foreign Affairs from 2003-07.

Prime Minister Recep Tayyip Erdoğan's nomination of Gül as a presidential candidate drew strong and highly vocal opposition from ardent supporters of secularism in Turkey. In May 2007, Gül's first bid for presidency was blocked by the Constitutional Court, due to concern over views Gül expressed during his Welfare Party years, and the fact that his wife, Hayrünnisa, wears a headscarf. However, following the parliamentary elections in July of the same year, which were won by the Justice and Development Party with 46.6% of the popular vote, he was eventually elected President on 28 August 2007 and was sworn in the same day, becoming the first openly devout Muslim President in the modern history of Turkey.

President Gül was born in Kayseri, a city in central Anatolia. His father is Ahmed Hamdi Gül, a retired air force mechanic, and his mother is Adviye Gül (née Satoğlu). His family has lived in the Güllük district of Kayseri for about a century. His ancestry/ethnicity according to a Çankaya Presidential Residence statement is "Turkish Muslim." Gül was also called with the name Cumhur (which means 'people') by his family.
