Nigeria is not a country someone will leave there political party and you expect there would be disagreement or change of power from the party, actually nothing will happen on that party because it will even be like say nobody comot for that party so don't worry about how the party he left will survive because they would always survive as they have always been, there was a time the River State governor do that to his party and they are still running as always, even if PDP has all the people that left them back they would not still win the upcoming election because the rulling party is not ready for the power to leave them now.
