that title should be shared between OBJ and IBB.
OBJ had the greatest opportunity to redeem and position the country among the first 30 in the world but was overwhelmed by greed,intoxicated by power and together with his group of overrecyled touts[they call temselves leaders/elites] squandered all in the name of "3rd term".He "fought" corruption by aiding and abetting it.
IBB is really the evil genuis and corruption personified. He legalised corruption by promoting it,and wasted the best election[free of trbal or religious colouration] ever held in nigeria.
