IMO, GEJ is not the worst president in Nigeria by any stretch. In fact I will go as far as to say that he is probably the best we've had in a couple of decades:

List of presidents from 1993 to before GEJ:

Ernest Shonekan
General Sani Abacha
Abdulsalami Abubakar
Olusegun Obasanjo
Umaru Yaradua

I think he has performed more than the above leaders although he is far from perfect and we can stand to be led more competently.

Why is he so disrespected compared to past leaders? Social media and the internet?
