I doubt that any of these people will be able to unseat Kidero in 2017... I have noticed that beyond all the politics (comparisons with Mutua and ODM party politics - where once he writes a cheque, all becomes well) there's some visible indicators that he is working: increased revenue collection, evidence of garbage collection; investment in health, education.
If the trend holds, and I dont see why it should not, by 2016, there will be very tangible results that he can ride on. So Sonko and Waititu would do well not to assume
