I think you understimate RUto at your own peril.
Ruto know he has huge window of opportunity with Kiambaa - and he aint going to slow down UDA entry into Mt kenya.
That is only coalition he wants.
The rest can keep talking.
For once Ruto has Mt Kenya - it almost game over.
So Kiunjuri/Kuria beef is realisation that if UDA sell - their bargaining power will reduce.
It not call for coalition.
It is an attempt to slow down UDA
