There is only one way to beat Ruto - unite all the oppositions (OKA plus Raila) plus Uhuru has to pull all stop to pull GEMA at least 30-40 percent of GEMA to Raila- anything else is not gonna work.
Ruto has managed to get both GEMA and Non-GEMA on his base.
If Raila continues to become anathema in Mt kenya - his candidature becomes impossible.
If Raila doesnt win ALL NASA stronghold back - his candidature becomes impossible.
For Ruto it's very simple. Get at least 60 percent of GEMA (realistic he is doing 80 percent).
Get Kalenjin and all former Jubilee zones. He is doing well in former Jubilee Zones except for Gusii and part of NEP (that traditionally relie on gov on power for relief food).
Then increase votes in places where Uhuru did badly - like Coast, Matusa and Western. He is doing well in Turkana, Narok, Kwale, Taita Taveta, Bungoma and Tranzoia.
Ruto if he wins any of OKA principles means Raila candidature is dead on arrival.
Another thing - OKA guys may become irrelevant - this going to disadvantage Raila (He need Strong OKA) - because right now Ukambani might split into 3 camps (Raila, Kalonzo, Ruto in almost 1/3 ratio); Western looks likely to split into 1/3 - again with slight variation.
With OKA severely weakened - Ruto wins in 1st round.
It's probably better if Raila adopt the 2020 OKA strategy where Kalonzo defend Ukambani, MaDVD/Weta defend Western - that mean playing for second round. That strategy saw Ruto lose Matunga, Kabuchai and Machakos. But if Raila cannibalizes OKA like he is trying to do - and Ruto is also busy cannibalizing them - then guess who is the loser - Raila. Ruto will get his 25 percent of OKA zone.Raila his 25 percent and Kalonzo-MaDVD will both get 50 percent of their stronghold- combined end up about or less than 10 percent of the vote. Ruto cross the 50 percent like Uhuru did in 2013 - barely.
As for turnout - we will have very low turnout - unless something changes - the registration of votes was disappointing 1.5m instead of expected 4-6m.
