I trust you don't all believe Raila is genuine in his push for "inclusion" and regional government. This is just a ploy to upstage Ruto's 2022 plans. The small tribes will all line up in Raila's corner as we can already see with Kalonzo. While also regionalism appeals to subpar kingpins Madvds, Weta, Joho, etc. Ruto is being seen as selfish wanting to keep all the power to himself. In case of any negotiations Raila will "compromise" and drop the regions, leaving PM as the red line.
This is just 2022, not reforms or inclusion. Ruto is damned if he does, damned if he does not.
