In Africa it is rare for a presidential poll to be held on schedule and results thereof announced promptly. Delays and postponements are the order of the day. In fact, it takes days and sometimes in excess of a week to announce the results of presidential elections.
The sad irony is that a lot of taxpayer money is spent before elections to acquire ostensibly fool proof technology that should in theory not only prevent rigging but also ensure prompt announcement of results. The story of delayed election results is so common that one begins to suspect that the problem is not with the technology but rather with the user. There seems to be an obstinate insistence on playing the game with the old rules.
