What do you mean lucky, is the Nigerian government unstable to the point that the Vice President has to worry about his position just because he is saying something that opposes the ruling opinion?
Well, I don't know how vast you're in the type of politics going on in Nigeria. The salient statement is "Don't ever outshine your master" I think that's even vividly captured in the book —
48 Laws of Power. It's an unwritten rule in Nigeria for the deputies never to go against their principals and this goes for the governors and chairmen too.
We saw a similar outplay of power between the then President, Olusegun Obasanjo, and the then Vice President, Atiku Abubakar. I believe you must've read the rift between them and how both became sworn enemies even while still in power. It was that bad with Obasanjo doing all he could to get Atiku impeached.
