Like it was uncovered many years ago; Ruto was fixed by PNU guys and the others [Raila,Maina,Hassan,US embassy] role was more gate-keeping. All the "key" witnesses against Ruto were PNU official of Nandi North, Eldoret North, Eldoret South and a few thrown here and there. These "witnesses" were handed over to human rights groups with long tales presented by PNU official led by one Njenga (lawyer).
Now that Ruto has buried the hatchet and is preparing to give GEMA another 5yrs; he will be fool to focus on Raila.
Beside I think he has extracted his pound of 'revenge' from Raila by backing Uhuru.
Now he need to tell Uhuru to either own up to the 'fixing' or he'll ran for PORK in 2017!
But will he? I doubt! He seem more interested in looting going on in this gov.
