The Ouru and Raila, Man Gidi will do what works for them. Their only worry is how to deal with the critical mass and what to do with their most powerfully and vociferous opponents in the likes of Ruto and Miguna. Once they have figured out how to sell their plan to a critical mass and how to deal with their critical opponents then they will slowly roll out their plan on how they will arrange themselves maintain their power. The rest is academic that we will discuss until the next time that new arrangements are neccessary.
Miguna? You've got to be joking. He has great entertainment value and can be a pest---"vociferous", as you put it---but beyond that? Where is he being vociferous right now, and what has the Handshake Man he swore in as "President" done to help him? Miguna's fights are right and proper. But the hard fact is that most Kenyans don't really care. Nor does Raila, whom he alternately castigates and latches onto.
If I were Miguna, I'd forget all the ingrates and go back to quietly practicing law. When Kenyans are ready for change---something that will require the sort of sustained kicks in the teeth that Moi gave them---it will happen. Right now things are bad but not bad enough.
