Take the north as a case study they have been in power but it doesn't seem to have improved their economic situation, the average Yoruba man is more successful than the average Northerner despite the fact that one has been in power for decades..

In America Obama was a black president but the lives of blacks did not change in any significant way...

Why do people think the right president can turn this country around?

It's a Matter of who the president is loyal to, who put him there
His own is to create an environment, ensure things are in place, that the system is working Do we'll get rewarded, otherwise punished else all goes to shit
