The Republic of Congo is voting to elect a new leader Sunday as incumbent President Dennis Sassou N’Guesso runs for a fifth consecutive term. The election could see Sassou N’Guesso extend his 42-year rule. The oil-rich country has not lived up to expectations as debt, poverty and unemployment rates have remained high. The election is the latest in a trend of octogenarian African leaders clinging to power. Sassou N’Guesso is the third-longest serving African president, only behind Cameroon’s Paul Biya and Equatorial Guinea’s Teodoro Obiang Nguema Mbasogo.
