I think it's just vitisho. They are trying to slow down Ruto. They recognize he is far ahead of the game. Raila is waking up and doing catch up. The rest are still waiting for Uhuru to endorse them...but like Ruto said...none of them have ever supported Uhuru or gema candidate..but somehow they want to reap where they didn't sow.
If Raila, Kajwang and NDP KANU when co-operating couldnt be able to impeach Saitoti back then, what makes them think it possible now . Beyond politics some of these Mps are personal friends to Ruto , when they personalize politics the outcome is the agitators will lose badly .Partly the reason Moi wrote of Raila as his successor was these kind of politics .
