I have given you a whole book written by Phds on kenya ethnic politics. It not that stupid. That is why many leaders have been rejected even when offered big post. MaDVD was rejected as Mp while he was Moi Vice President for 3 months. There are many many examples. There is a nexus btw TRIBE AND TRIBAL INTERESTS. That is why most leaders have to work hard, show some development and generally be on top of community interests. The moment you pursue personal interest that are inimical to community interest - you lose the plot.
A good example no 1)Uhuru - GEMA have 1M diaspora lifes and properties on cross hair in case of fallout btw Ruto and Uhuru. That is community interest.
Uhuru maybe no longer can tolerate Ruto. That is personal interest.
Uhuru therefore for last 3yrs has really struggle to dislogde Ruto from Mt Kenya hearts and minds. His personal interest is clashing with community interest.
Example no 2) How Moi died a Lonely Man.
Understand what happened to KANU. Moi for many years had built anti-GEMA coalition - who were his main competition. There was agreement that either Kalonzo or Saitoti or Ngala or MaDVD or even Raila would nick it after Kalenjin. This was coalition btw Luhyas, Kalenjin, Kamatusa, coast and Ukambani - including Gusii. Raila came late and I don't think he was acceptable. He would have face the same revolt as Uhuru didi.
Now what Moi did - was to turn 360 and endorse a Kikuyu. That was huge betrayal of all those communities and their hopes.
It akin to what is happening in central - if Uhuru was to turn 360 and endorse Raila. It will lead to a revolt...which is already underway anyway. Uhuru/GEMA have spend a generations building anti-Raila coalition and therefore to turn 360 - and endorse Raila would be seen as ultimate betrayal of the cause.
Kikuyus are wonderng like Kalenjin if Uhuru has been be-witched or got seniled or lost his mind but I think Uhuru is playing a game here. It doesn't make sense to them.
If he insist on Raila - he will end up like Moi - derided even by his own people. Moi spend the last few years wondering what he ever did to Kalenjin for them to hate him - yet to him he had done a lot (true) for the community.
You say KANU was anti-GEMA coalition so they rejected Uhuru. But entire Kenya was taught tribalism yet you know say it is about class. Do you not see the contradiction? If Gema will never trust Raila because of Kibaki and Uhuru propaganda - what makes Kenyans reject their tribal leaders and embrace one rich hustler? These are the same Kenyans - they cannot be conservative and reject Raila then be liberal at the same time to enbrace class. There is no basis for your arguments. Tribe is very entrenched.
