A supporter of opposition presidential candidate Nana Akufo-Addo shows off her teeth, decorated in the colors of his New Patriotic Party, during Akufo-Addo's final campaign rally ahead of Friday's presidential election, in Accra, Ghana, Wednesday, Dec. 5, 2012. 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 President John Dramani Mahama, a former vice president who assumed the top post in July after the death of president John Atta Mills, and former foreign minister Akufo-Addo who lost the presidency by less than 1 percent in 2008.
