NASA had to go because Raila had no intention of honoring his MOU with Kalonzo and MaDVD. The rest are the details. I think even ODM will also go because Raila knows it no longer viable. I am thinking Raila will try to gobble the remnants of 90s opposition - considering Jubilee(KANU) is very strong now. I think that is what he is eyeing thro his trojan horse attack - get a grip of GEMA leaders like Martha and Gitobu - and those who may not like WSR. It not gonna work because Uhuru is the now so dominant - he basically command nearly the entire GEMA - except maybe Meru?
Raila should consider retiring and handing the mantle to a younger Luo or Joho.
