Since Nigeria's independence from the UK in 1960 there have been numerous coups and rigged elections.

This poll has brought to the surface dangerous religious and regional differences.

The outcome may be disputed by some and there is still a fear of violence. But many Nigerians feel for the first time they have the power to vote out a government that is not performing well.
