1. MauMau leaders were well accepted by their exploits and what they doing fighting Brits colonialism. There was no question of forcing people to support them. People just did. Also don't forget even famous and well known chiefs/persons had their heads chopped off for being traitors. Uhuru is almost there. The power he wields as President notwithstanding.
2. JM had not really risen to the point of being a leader as seen from Kikuyu eyes. He was more like Moses Kuria. Championing for well known issues and making life uncomfortable to Kenyattas thieving.
3. Matiba And Kibaki had split Mt. Kenya loyalties. Therefore in all instances there is nowhere anybody imposed themselves. Jomo was widely accepted due to historical circumstances of those times. But he was lucky he got arrested when he did as MauMau had resolved to chop his head off for being traitor. Also read Bildad Kaggia book to understand how Brits schemed to have Kenyatta as the leader.
Anyway, point is Uhuru cannot and will not impose his deranged view/BBI Plan without opposition. He will implement BBI without Mt. Kenya support or votes or consent.
May i point to you that currently when Uhuru visits Mt. Kenya he's being accompanied by enhanced security including those GSU/Soldiers Lorries. Things are thick.
Finally, William Samoei Ruto aka Hustler has found himself as a man of circumstances. A man of the moment. Mt. Kenya view him as the incoming leader and have adopted him as such. It is NOT HIM WHO HAS BRIBED OR STOLEN UHURU'S SUPPORT, but rather circumstances have brought him to where he is. This is the whole of Mt. Kenya agrees and acknowledge they cannot produce the next president and therefore they are better off supporting/adopting another person outside Mt. Kenya. That person happen to be Ruto. Second reason is that Uhuru has DELIBERATELY AND SYSTEMATICALLY SUPPRESSED any alternative to himself within Mt. Kenya. Therefore people have to look for alternative: after all leadership hates vacuum.
To me Kiunjuri is STILL NOT YET A MT. KENYA ALTERNATIVE to Uhuru. He could be but he has a way to go. Maybe soon he will surprise me and truly grab mantle from Uhuru. In other words there is a leadership contest and transition taking place in Mt. Kenya and Ruto just happened to be the man of the moment. Ruto is being "temporarily accepted/adopted" as Mt. Kenya leader until a more solid and acceptable leader emerge after Uhuru. Uhuru need to go home and smoke his stuffs so that Mt. Kenya move on:can have a leader for the future.
Finally, absolutely and absolutely I HAVE FOUND NO ONE EXCITED that Uhuru can be (will be) Executive PM. No one. Most dismiss it as "wana.." (utoto/childishness). No one is buying this thing. And if you see Mt. Kenya openly asking themselves "kwani ni familia ya Kenyatta wanaweza ongoza tu!?" just know ni kubaya.. No one is interested in maintaining Uhuru leadership any longer than its necessary. No one.
Ruto is caught in-between Mt. Kenya leadership transition battle.
What history shows Gema are lead by consent? Mau Mau history of Dedan Kimathi, Generals Mathenge & Kago, Jomo, JM Kariuki, Kibaki vs Matiba, etc show they follow the strongest leader as all other groups. Otherwise they should have gone to JM. They defied Kibaki for selling Mdvd over their own prince Uhuru... which is a point against Ruto. Smashing Waititu or Kiunjuri decisively actually attracts following contra to expectation.
The trail of deserters shows Ruto is not doing too well. Ask yourself why they all deflect the attacks to Raila if Uhuru is so unpopular. Gema will wind up firmly back in Uhuru's corner. Ruto's chance to pick a Luhya or a Kalonzo is also closing. Uhuru 2.0 is a very poisonous chalice he cannot duck.
About 10 years and democracy... you're wishful. Here we have ample history of octogenarians getting elected by their tribes to a man. Uhuru is hardly 60 and Mt Kenya is not any l)
