On May 29, Muhammadu Buhari was sworn in for his second term as President of Nigeria. The assumption of democratic theory is that in an election, the electorate considers different options and settles for the one that will best advance their interests.
If one of the options is an incumbent, then the electorate judges to what degree their interests were served during his or her expired term, and whether any one of the other candidates could do better in that regard. The process of weighing the pros and cons of available opinions is supposed to be done objectively and logically, and to be driven by self-interest.
