You're wrong. Public service the qualification and tribe matters. In fact it up there in constitution. In private sector go for most qualified. This guy is qualified - well regarded in KPA - but Murkomen is appointing authority. For most people they will see his surname.
So gov has to consider both qualification and the tribe - sometimes they can compromise on qualification to balance tribes.
Constitution demand civil or public service MUST have kenya face. Kalenjin and Kikuyus are already over-represented in gov - and it appears the trend will continue. Instead of correcting it - it getting compounded.
Ruto should hire himself an ethnic advisor - who will go through all his appointments and minister appointments - monitoring compliance way before gazettement. That way mistakes dont happen - and ministers dont start appointing their friends, tribesmen and etc.
