In RV ,am building in his 2017 numbers,he got 0.9 M votes,they can only go higher factoring the 30% gema votes in Nakuru,Laikipia,kajiado as well as the additional new voters.
Western,I start with busia where 80% is Baba,if the 460,000 voters,Baba starts with a cool 350K votes,Vihiga he gets 70K(Luos around Nyangori and Luanda).Kakamega is 60% Baba ,that's about 300K for Baba.Bungoma Baba will make 40%,giving him about 200K votes,if you total that overall comes to about 0.9M votes.
Coast is dominantly ODM,Baba will do well in Mombaa and kilifi counties scoring over 65%.Both counties have over 1.2 registered voters and the two will give Baba close to 0.7M votes.Taveta,Kwake,Lamu & Tana river will give Baba additional 300 K votes to make it 1M for Baba in coast.
Eastern,with Kambas 1.6 registered voters,1.1 will come out to vote Baba,add 35% of merus,embus,Tharakas which is about 400K.overall Baba gets 1.5 M of eastern votes.
NE,Baba will manage over 65% of the 0.7 registered voters whisc is about 0.4M voters,all leading aspirants are in Azimio.Tgey tend to go with the winning team.
I say the magic number is 30% for Baba in gema nation,this is about 1.5M votes(central, Meru,Tharaka,Embu,Nairobi and gema in RV).,and it's the game changer.
Game over.The gains Ruto has made in coast and western are insignificant to the overall vite basket,1% gain in western or coast is not equal to 1% gain in central gema.
