Kuria/Ichungwa come from Kiambu. Surely Uhuru cannot be replaced by someone from Kiambu. Also Nyeri is out. The counties competing for PORK amongst GEMA are really Muranga, Kikuyu diaspora and Meru.
Ruto biggest worry is really Muranga - because Wa Iria, Peter Kenneth and maybe even James Mwangi - could spring up and rally Muranga to go for it. So Alice Wahome could make a good counter-punch for Ruto. She is a tough women.
Mwangi Kiunjuri is great - because first Kikuyu diaspora will rally behind him - they've been misused for so long and when shit hit the fans - it's them who suffers. It also help Kiunjuri comes from Nyeri - and so can easily win over Nyeri-Kirinyanga. So DPORK in Kiunjuri will rally diaspora very strongly and will also be very competitive in Nyeri-Kirinyanga-and even embu.
So Mwangi can easily rally Nakuru, Laikipia, Nyeri and Kirinyanga. Kiambu don't expect PORK and will go 50-50 if Uhuru was to go rogue. Muranga is where Ruto may struggle if Pajero is right that Kikuyus will have their candidate. It's likely such a candidate could come from Muranga.
That leaves us worrying about Merus and Kithure Kindiki. Kindiki needs to be given big post - and he will be fine. Maybe AG or Speaker or Deputy PMs if Raila's BBI is the way to go.
he may want to cultivate a working relationship with URP and give kuria/ichungwa a run for their money. he has no following in centro; he has no cards to bring on the table. he might be reading mudavadi/kioni script before the show begins. very foolish man, kiunjuri.
