Please forgive me if I get my analysis wrong. Atiku seems to me like some APC aspirants in just concluded primary election awaited all day long for Buhari endorsement. Since his emergency as PDP candidate, I have not seen him make any serious move expected of opposition candidate instead it's ruling party candidate and Labour Party that's making some important move.

Whichever way, they are gonna loose.

Atiku has his game plan. Even before the PDP primaries, he was not making noise. It was Obi, Wike and Tambuwa, but like a snake he struck at the last minute.
Staying in Dubai na his 2023 strategy.

Same thought but excluding Wike was their undoing. Wike seems to be the engine room of the Party for years and excluding him really affected the Party in many States.
