Undoubtedly, the events of the 2007 general elections coupled with the verdict of both local and international observers clearly demonstrated that the entire electoral process was controversial, thereby making the election flawed. The concomitant effect is a crisis of political succession, which has always been the bane of Nigeria's march to democracy. Thus, the thrust of this paper is an in depth analysis of the elections vis-à-vis political succession. After an introductory overview the paper proceeds to a conceptualisation of political succession, which forms its theoretical framework. Part three dwells on the flawed elections, discussing what went wrong. The final section calls for the restructuring of Nigeria's electoral system and recommends a number of remedies. The paper, however, infers that without a credible election sustainable democracy in Nigeria may become a mirage after all.
