Battle ground is Kiambu and Kiambaa which have 170k votes.
Nyoro got 240K votes in 2013 gubernatorial race against Kabogo 480k.Nyoro ran on a NARC ticket against the TNA three piece suit.That was maybe about 20% or so.He is not a political greenhorn.
Raila got 7% in 2017 presidential vote kiambu county.Turnout was 83% I think.
Governor Nyoro start with the Raila vote advantage of 10% against his competitors.He may get lots of votes around kikuyu kabete and limuru.If they go 5050 with matangi he has second advantage.In Gatundu Uhuru still has some support there so it's matangi Nyoro and kuria 30:30:30 which gives him third advantage.Jungle takes thika.Kabogo takes ruiru and Githunguri.Kabogo and jungle go 30:30:30 with matangi in Juja due to UDA advantage.
Nyoro wins.
