Personally, I think Nigerians have tried, I am sure you won't blame me/them for loosing hope in a student that has failed in all the subjects, consecutively for 6 years. I/They have done my/their best, no sentiment attach, all of them(Politicians) are same of same but at this point I/We just need to try and taste something else. Doing something the same way and expecting a different result - has been proven to be the biggest level of insanity. Supporting Buhari/Prof. all the way.
