A poster showing the picture of Nigerian president Goodluck Jonathan is seen at the launch of his campaign in the central city of Lafia, Nassarawa state February 7, 2011. To the sound of pounding reggae music in a small, dusty town in Nigeria's "Middle Belt", President Jonathan began campaigning for an election in which he hopes to upset the natural order of politics in Africa's most populous state.
