What are they objecting? Mashada rumors? And according to you 90% - 60MPs - from Mt Kenya are in Tanga Tanga. This is what - 40%? Of course you ignore all the governors and CS's who have more say than MPs. Where do Kiraitu, Kimemia, wa Iria, Waiguru stand about the gossip? What about Uhuru?
Anyway i think if the gossip is correct - parliamentary with mandatory tribe & youth inclusion, 40% devolution, high integrity bar, cap on MPig perks, ... Dr No and his band of 30 thieves will lose in referendum. Only Kalenjin and a few Kikuyu will oppose. Even Meru or Mbeere or Kiraitu, Duales, Nanoks - everyone else is fed up with the Kikuyu-Kalenjin duopoly of power. Ruto would need 100% Kalenjin + Gema to stand a chance.
But this is still only gossip so we can't have a meaningful debate.
