Eugene Wamalwa delivered Trans Nzoia. Despite being 30% Kalenjin and Kikuyu, Raila beat Ruto. Implies Bukusu there voted 75% Raila.
Uhuru I agree delivered AZIMIO MACHINERY - the cash, organization, zoning, etc. If Raila wins he owes the most to Uhuru the man.
If Ruto wins he owes the most to Gema the group.
