The way we had it doing 1993 presidential election, when MKO Abiola and Baba Gana Kingibe of Social Democratic Party (SDP), were the aspirants of their political party.
Can we have the same in a well divided Nigeria of today.

i dont think it will be possible in this country,even some states this cannot work not to talk about the country

Simple answer No

Tinubu tried it in 2015 but even buhari that is a religious bigot told him to backtrack

The reason is that Nigeria is externally divided across religion and tribe South and North Christian and Islam

These lining must be carried along otherwise the nationhood would be threatened

The south is the major zone bringing the funds of this country and you can not exclude it from running government as president or vice

80% of the south is Christian majority so you can't pick from south without carrying the majority religion along

Tinubu learned this the hard way when he insisted he can force Yoruba Muslim on the south but was told to retrace his step because yorubas are not the only region in the south
