Yes,Orengo is very right.Mt Kenya mafia are out to retain powerful presidency for good.They know they have the numbers but only need another single tribe to win.
This is the game plan,create a NARA like PM,entice kambas or Luhyas with the PM post while retaining the powerful presidency.They know
Raila nor Ruto cannot play second fiddle again.Watch out for PK ,Kalonzo or Musalia ticket.
