In 1999 the nothern military leaders that governed Nigeria Zoned the presidency to southern Nigeria and micro zoned it to South-West when they prevailed on Dr Alex Ekwueme to step down for Obasanjo whom they granted presidential pardon.
In 2008 Obasanjo and PDP zoned the presidency to north- West when he Obasanjo personally picked Umar Musa Yar'adua as PDP choice for candidate and rallied support for him,he eventually emerged winner.
Yar'adua died in office leaving Dr GoodLuck Jonathan to continue in his stead.When he finished their joint ticket,he stood election on his own,PDP again zoned the presidency to South and Microzoned to SOUTH-CENTRAL.
When Jonathan won and finished in 2014 ,he want to go for second time North-West and North-East revolted and said it is their turn,they rejected Jonathan and went for Buhari with the help of other Nigerians Buhari won.
Buhari went for second term both PDP AND APC zoned their ticket to the north,North-East and North-West.No southerner contested as president in major parties.
Buhari,a nothern muslim, will be finishing his second term of eight years come 2023.
Equity demands that both PDP and APC should field a southern christian presidential candidate.But they failed to do so.PDP went for a northern muslim against their own priciple of zoning,hoping to retain presidency in the north after,Buhari another nothern muslim would be finishing his eight years presidency.
APC went for tinubu a southern muslim,and withouth being sensitive to the burning issue of religion in,he chose a muslim running mate.
So far only THE LABOUR PARTY mate all the requirement for a balanced presidential ticket in terms of equity and fairness as it concerns region and religion in the current Nigeria political cycle.
VOTE PETER OBI FOR PRESIDENT TO ENTHRONE EQUITY AND FAIRNESS
I AM CHIEF OBJLIVE

In 1999, presidency was not micro-zoned to the SW. Aspirants from all over contested in the PDP primaries and Obasanjo won.

Even Tinubu to step down too and vote for Peter Obi.
