The grave man simply has no balls. I hear Tinga wanted to shunt him aside by offering Nairobi's governorship to him. That way, Tinga would be free to choose kina Peter Kenneth or the Iron lady as running mate so as to be even remotely attractive to the central Kenya folk.
He is like the Ruth of the bible, where Tinga goes, he will go, whatever Tinga orders, he will do. Spineless chap.
Great men are not always wise, neither do the aged understand judgement...
