The coalition of different parties formed by Atiku and Peter Obi seems like a correction of their mistakes to me, because had this been done before the last election, I doubt if APC would have won the last election, because the last 2023 election's analysis for these three parties isn't far away from each other: APC was at 37%, PDP 29%, and LP 25%. Imagine if PDP and LP had merged then?
Even with a coalition party, it won't still work since our electoral system lack credibility, there is no free and fair elections as the electoral votes will always be manipulated to the advantage of the governing party. The reason why coalition party worked during the era of Goodluck Jonathan was because he was a peaceful man and values the lives of the citizens otherwise nothing would have stopped him from winning the 2015 elections but he said his ambition is not worth the blood of any Nigerian.
Had it been that PDP and LP merged together, they would have only formed a strong opposition against the APC but APC wouldn't have lose the election when Buhari was still President. However, the only way that governance can be rotated is when we start practicing a two party system like the US because that is the only way to form a formidable force against the other party.
