After five coups and decades of stagnation, the West African nation of 25 million is now a pacesetter for the continent's efforts to become democratic. Ghanaians will go to the polls on Friday to choose between four candidates, including Mahama, a former vice president who assumed the top post in July after the death of president John Atta Mills, and former foreign minister Nana Akufo-Addo who lost the presidency by less than 1 percent in 2008.(AP Photo/Gabriela Barnuevo)
