I don't recall anywhere where Ruto has been implicated. If Uhuru rigged the election - or killed somebody - is Ruto now guilty. Ruto NEVER dealt with Sonko - except - at arm lengths. Uhuru is the one afraid. He was drinking with Sonkos, Moses Kuria and that kind of company.
As for his strategy - it possible Sonko to even move to ODM - if Ruto is committed to Wanjiru (GEMA).
I don't know what his strategy here is - obviously apart from fighting the impeachment - he has two options - go to Machakos or stay in Nairobi.
If he stay in Nairobi - Ruto will find it difficult to keep him - because GEMA in Nairobi will want governorship - and Raila will be willing to deal - so Ruto has no option except back a GEMAn.
Sonko will probably try to go ODM. Sakaja has left Jubilee for ANC.
If he goes to Machakos - he will need Muthama - hence Ruto - and if Kalonzo is still strong - he will run to Kalonzo.
The by-election on march will tell us a lot. If Ruto win most of them including MCAs seats - then he can as well be declared 2022 winner - and the presidential ballot can be used for BBI. If he fails - then we are looking at a dog fight to the end.
If Sonko is fighting for Ruto, why is he implicating Ruto in 2013 and 2017 election rigging? Read my signature.
