Yes his only problem was Kiambu to replace Uhuru and a kikuyu - that was a double whamy. I am sure he will be finance minister. I like the guy a lot - very sharp, meticolously and nonsense.
I am torn btw him and Ndidi as the future of Kikuyu nation.
But RIGATHI NI SUB MARINE. I would advice Ruto not get into such succession games. Rigathi is not likeable but he is experienced. And he is old.
Just give all the 3 - big jobs - and let each prove themselves.
I feel Ichungwa lacks that Killer instinct that Ruto , Rigathi and Ndidi posses. He is too nice or gentlemanly. Very likeable but cannot snap someone neck if need be - and that is normally for me the big redflag if someone is ready for rumble tumble that is cuthroat politics - MaDVD type or Ruto type. You need to have no compunction slizing necks that block your way. If you're not cutting throats - your throats is being cut.
If he can work on killer instinct - he is going far - otherwise he is brave.
As for Moses Kuria - he lacks personal discipline, is a drunkard and cannot keep a secret - he is hopeless except as utility player.
So for me - Ichungwa (more meticolous/discipline/careful), Rigathi (submarine, maumau, mungiki, 100 percent killer instinct like Biwwott), Ndidi (charisma, brave, go-getter, killer instinct).
I would put my money on Ndidi Nyoro (he reminds me of Ruto) - just need to work on his muranga accent. Then a tie btw Ichungwa and Rigathi.
