This is what I say would happen. The idea here is simple, to disefranchized as many voters as possible - living within strongholds. Moi's 90 playbook. Expect to see chaos in Kiambu - where more than 10% of residence are non-GEMA and would vote Raila. Expect the same in many places including Nakuru, Kericho, Nandi, Bomet - where migrant workers working in flower farmers or tea farmers - will be kicked out. Also expect some kind of zoning to happen in main towns - nairobi, mombasa, eldoret, kisumu and eldoret - where slums thugs will square out.
We shall be see another exodus back to "home" counties by many people.
