Omwami, you seem to have had a moment of clarity today. What happened? Did you finally manage to pull your head out of your backside (which must have taken a lot of greasing with Kimbo/Blue-Band or whatever it's called), or has Raila taken a short break from dancing all in, on, and around it?

Whichever it is, I mostly agree with your analysis.
Some people actually think that a new constitution actually means anything to the Owners of Kenya and do not see that the Owners will allow a small amount of "change" just to let some steam out of a bubbling pot that might endanger them. Kibaki knows what any "leader" in Sub-Sahara Africa knows---that there is almost no limit to the extent to which you can shit on the heads of the ruled and they will just take it. If Kenyans were even just a little less tribalistic or a little less sheep-like, they might be able to stop Kibaki in whatever sort of "mta do?" path that he chooses. Sadly, the quality of available stock does not promise much; so we cannot look to the unthinking, tribalistic sheep to stop Kibaki from becoming another Mugabe.
The reason I only agree "mostly", and not wholly, with your analysis, is that it does not adequately take into account Kenya's history and the relationship between the Owners and the sheep. Some people think that Kenyans managed to get rid of Moi, the Master Mass-Murderer At Election Time, after 24 years but that is not so. What happened is that (especially after certain Western countries took a tough line), the Owners, who saw their interests threatened, had a chat with Moi: "Brother Arap, you are now one of us. When our interests are threatened, so are yours. You have managed to nyakua enough in 24 years. Why not quietly enjoy it now, like the rest of us. Not to worry, we'll get the right sort of fellow into State House. You will have almost all the perks you had as president and a few more. In fact, for starters, why not keep that nice house? More importantly, you will never have to face the law for all the heinous crimes you had carried out on Kenyans. Surely, that has to be better than going out in the traditional African way. What say you, Brother Arap?". The rest, as they say, is history.
I am here trying to say two things. First, Kibaki, although he has been around for ages, is president, has stolen more than his fair share and so is very wealthy .... has never actually been one of The Owners of Kenya; he's just the boy they put to mind the shop-front while business is conducted at the back ... unlike Uhuru, whose daddy had already done all the "heavy lifting" when it came to robbing Kenyans.
As an aside, I'll say this for Jomo: he had his bit of killing, he was a thieving scoundrel, he started "eating" (a true Kenyan passion), let the country go to pot while he was busy with a newly acquired schoolgirl-wife (a certain Ngina or something)... but the wholesale slaughter of citizens at election-time was never his sort of thing.
End of Aside. Second, it is not the unthinking, tribalistic sheep that populate Kenya who will clip Kibaki's wings; the real call will be made by the Owners of Kenya. There is only one thing you can rely on the sheep to do: even while starving (supposedly drought), not having even clean water to drink, suffering from easily preventable illnesses, ... they will happily slaughter each other because "or man has to get into State House".
