Yes big stakes - I can think of big targets in UDA - Ruto himself - Dennis Itumbi (releasing the gov intelligences and secrets) - and Chirchir (IEBC) - on matters UDA/Election - they need best of security. They fear Chirchir for no good reason. Definitely they will try to intimidate and block Ruto financiers account - this they did to NASA.
As they become desperate, as it become very clear that Ruto is hard to beat, expect anything.
They have tried Kiambaa - nothing. Next they could even start PEV - but people are ahead of them - because they have showed their hand.
