NIgerian elections- Will the country remain stable?

Nigerian elections are set to be held early 2015. They are set to pit Muhammadu Buhari, a northerner, and the current President, Goodluck Jonathan. More precisely, the election willl pit the christian south against the muslim north. Traditionally, Nigeria has exercised a gentleman's power sharing agreement, in which power is rotated between the Christian South and the Muslim North. However, this arrangement was broken when Goodluck became President and succeeded the late Umaru Yaradua, to the chargrin of many northerners. In early 2013, Nigeria became Africa's largest economy after it rebased its economy, which is now half a trillion dollars. However, instabilities in the north, occasioned by the Islamist terror group Boko Haram, have served to overshadow the tremendous economic gains that the country is making.
