Senegal's outgoing President Abdoulaye Wade waves as he leaves the presidential palace, ceding its occupancy to newly inaugurated leader Macky Sall, in Dakar, Senegal Monday, April 2, 2012. Sall took the oath of office Monday in a ceremony held one week after the country's longtime incumbent conceded defeat only hours after polls closed. The presidential runoff vote solidified the country's reputation as one of the few mature democracies in western Africa, where the unpopular president was ousted at the ballot box instead of a coup.(AP Photo/Rebecca Blackwell)
