I think we have not been asking enough questions abou how the then governing party, the PDP was getting its 'account breaking votes' from.

According to analysts and observers, the 2015 elections was the one in which the Nigerian people registered their highest ever participation and one in which a lot was at stake for both sides, so literally, everyone brought his 'A' game.

But ultimately, looking at the result, you will realise that consistently, the votes of two particular regions that have hitherto been the party's stronghold were not upto the numbers anticipated from them: I am talking about the SE and SS.

Come 2019, these regions' votes diminished further from what was obtainable in 2011 and 2015.

This gives rise to the question, where was PDP getting those votes from?

Please check the wikipedia result of all elections from 2007 to date.
