Raila Odinga, Kenya's veteran opposition leader and one-time prime minister, is taking his fourth run at the presidency in an election next week. The 72-year-old has been a mainstay of Kenyan politics since the 1980s but has never achieved his presidential ambition, his career emulating that of his father, Jaramogi Oginga Odinga, who led the opposition for three decades but never the country. / AFP PHOTO / FREDRIK LERNERYD (Photo credit should read FREDRIK LERNERYD/AFP/Getty Images
