You work with what you have - not what you wish.
Kidero and Migori former governor are perhaps the only Luos who can stand up against Raila and survive - thuggery and all that.
Migori is a thug - so Raila cant take thugs to him
KIdero is also a thug - and very wealthy - and very arrogant - raila cant tell him nothing.
The last Luo to challenge Raila was one KANU mayor Oyile or something - he had Baghdad boys that send Raila from Kisumu to Kibera.
Raila brought his violence to Nairobi having been defeated by some Kisumu mayor /councillor.
Luo politics plus siaya and part of western is very very violent;
Politicians hire gangs;crooks; it violence after violence;
Odingas have made them thing violence is good.
In Kalenjin if a politician engage in base insults or violence - he will not be voted. Isaac Ruto was only violent kalenjin politician in my recent memory. Only Raila type who employ goons. He was in 82 coup with Khawale and Raila - these former student leaders - kalenjin huwezi make. You better be a christian humble man.
There is time for war - rare times - but in peaceful times people expect politicians to come humbly and beg votes.
