Voters collect ballot papers representing the 14 presidential candidates as they prepare to cast their votes for president at a polling station in the Cambarene neighborhood of Dakar, Senegal Sunday, Feb. 26, 2012. After weeks of riots, Senegalese voters began casting their ballots Sunday in an election that threatens the country's image as one of the oldest and most robust democracies in Africa. This normally unflappable nation on the continent's western coast has been rocked by back-to-back protests following the decision of its 85-year-old leader Abdoulaye Wade to seek a third term.
