According to data from the Independent and National Electoral Commission (INEC), at least 13.5 million Nigerians were discovered to have voted manually in the 2015 presidential election.
The analysis of the data revealed that 75 percent of votes cast without PVC were in states won by the then candidate of the All Progressives Congress (APC), President Muhammadu Buhari.
The data, obtained by DeepDive Intelligence, also shows that Buhari won in nine of the 10 most-affected states.
Former President Goodluck Jonathan, Nigeria’s first incumbent president to lose a re-election bid and Buhari were the two major contenders in the 2015 historic presidential election.
Of the 31,746,490 accredited voters in the election, 13,536,311 representing 42.6 percent of voters voted without biometric accreditation.
Out of this number, 10,184,720 votes are from states won by Buhari and 3,351,591 votes came from states won by Jonathan, the Peoples Democratic Party (PDP) candidate, representing 75 percent and 25 percent of accredited voters respectively.
