Opposition chief Raila Odinga may vie for the presidency in 2022 if his quest to amend the Constitution sails through.

It will be his fifth stab at the country's top seat but one thing the former prime minister should least expect is majority support from the vote-rich Mt Kenya region.

During the burial of Migori Senator Ken Oluoch on Monday, Embakasi East MP Babu Owino revisited the debate over whether Central Kenya has a political debt to pay Raila or not.

In 2002, Raila wholly supported Mwai Kibaki for the presidential contest and Kibaki succeeded uprooting then president Daniel Moi's regime. Were it not for Raila's vigorous campaigns, perhaps Kibaki may not have become president.

So does Mt Kenya region has Raila's political debt to pay for his support for Kibaki?

Kibaki and Raila did not enter into an agreement where he was expected to support Kibaki and Kibaki thereafter would support his quest to become president.

The Narc coalition was a coalition of like-minded politicians who were out to end KANU's rule since independence and there was no arrangement of paying any political debts after Kibaki's departure from power.

This is unlike President Uhuru Kenyatta and his Deputy William Ruto's 2013 agreement where the two signed a pact that said Ruto would rally Rift Valley to back Uhuru's presidential bid before Uhuru would in 2022 rally Central Kenya to vote for Ruto.

Raila had not any binding agreement with Kibaki and he should therefore not expect Mt Kenya region to back him in 2022. This can only happen if Uhuru agrees to rally members of the Kikuyu community behind the former PM following their recent meeting at Harambee House in which they agreed to work together.
