And it will continue that way as long as mwananchi keeps asking for it.
For the Kenyan voter, character and integrity, past performance, real potential for future performance, ... anything resembling objectivity ... never matters. Votes are given on the basis of who has bought busaa for the men and sugar+tea for the women, "the person from our place", "our tribe vs. that tribe", who has promised (falsely and for the 100th time) to tarmac this road, etc.
Kenyans always wail about their politicians--"they are corrupt!", "they are selfish!", "we will throw them out at the next elections!"---and then, when they get the chance to change their "leaders", proceed to replace the "bad" lot with a similarly bad (or worse lot). So, in the end, nothing really changes. On the contrary, the "leaders", knowing that they might not return, will eat as much as they can while they can; and they know nothing will happen to them, because, when called to account for their mischief, they can readily rely on "money has been poured to finish our people!". That means the prospects of leadership-driven change are next to zero; change will have to come to be bottom-up.
In Africa, the bottom-up change usually means unemployed youth taking to a "rebel army" or other unpleasantness. The other way is that the people get so much crap beaten into them that they decided that just for once they will use their heads: in Kenya, that was Moi urinating and pissing on heads for 24 years.
At present, neither the voter nor his/her elected "leader" shows the slightest inclination to change in the manner required. In such circumstances one might as well just wait for evolution to work its thing.
