I don't think Uhuru can risk a rebellion in Central/Mt Kenya. That is why he was blowing hot & cold. He was actually pleading for mercy because he knows
1) Mt Kenya proletariat have said NO to his politics post-2017 elections
2) The majority of leaders are with the people in rejecting Uhuru politics that are hard to comprehend.
3) Mt kenya are accusing Uhuru of under-delivering compared to Kibaki - SGR as you well know avoids Mt Kenya - and all big ticket stuff - nothing is happening there - Kibaki was blantant tribalist - who spent a lot in Mt kenya - while Uhuru has tried to be fair - I think he has been most fair of all presidency.
There is nothing more hurtful than to be rejected by your own people.
Let wait for BBI to be released. If there is lots of hue & cry in Mt Kenya - Uhuru will kill it.
Uhuru risk losing all - he loses Mt Kenya and he is GONE kaput in great shame - and Kenyatta's will go back to irrelevances - like the Mois in Kalenjin land.
Ruto has to play smart like he has done - attack Raila and ignore Uhuru folks shadow-boxing at least publicly - don't give him the excuse to win back Mt Kenya. Don't pull punches on Raila because there is huge anti-Raila following in Kenya esp in Mt Kenya.
Kiunjuri and Ruto have it coming. They don't have the numbers to stop BBI. Once it passes, there will be no almighty president let alone VP - what will Ruto be offering Gema? He could always front Kiunjuri as PM - and square with senile Raila for ceremonial president
As long as Raila is ready to sacrifice to scuttle Ruto the latter is in serious trouble. Uhuru just needs to hold Gema and pit non-Gema. Easy peasy.
