All that is true, but is there any serious indication that the citizens really wish to have something different? Kenyans are always happy to show up in great numbers for political rallies. And, as is happening right now, they are even happier to engage in violence and all sorts of mischief on behalf of their chosen politician. But how many have you ever seen demonstrating (or taking any kind of action) on service delivery, corruption, etc.?
Nor do Kenyans ever vote "right". Kidero already knows which votes he can take to the bank: those from NASA-affiliate tribes. His performance on the job matters little to such voters. Likewise, the Jubilee candidate for Governor of Nairobi can bank on certain tribal votes, regardless of potential to perform. And all that extends to the national level: votes for Raila-Kalonzo vs. Uhuru-Ruto will not be cast on the basis of performance or potential for performance. Even some those who have been badly let down by the government---e.g. the starving of Baringo---will still vote for Jubilee.
When Kenyans finally decide that they have had enough and want change, they will act accordingly and end up with real leaders.
What kind of legacy will the top leaders be proclaiming at this rate?
Irrelevant in a place Kenya. The only thing that matters is eating right now.
