Honestly Somalis and Kikuyus have a major beef going on economically,Its reasonable to say Somalis are taking over almost all sectors apart from matatu and pombe,Somalis are in real estate, transport, logistics,Oil ,banking, supermarkets, distribution even farming etc,Kikuyus have already lost to somalis , simple in 20 years Somalis will control everything in Kenya ,so its not far fetched they support Ruto.
Kikuyus have been left in retail and mali mali, hawking etc,
