Ghana votes as president Mahama seeks a final term

By Kwasi Kpodo TEMA, Ghana (Reuters) - Ghana voted on Wednesday in what looks set to be a tight race as President John Mahama seeks a second and final term against the backdrop of a West African economy that has slowed since he took power. Lower global prices for Ghana's gold, oil and cocoa exports and a fiscal crisis caused the slowdown and it has made Mahama's government vulnerable to the challenge from the main opposition leader Nana Akufo-Addo.
