Kalonzo biggest problem - he is a social climber - he really want to appear near cool billionaires of Uhuru and Gideon - but they are selling him to Raila. Raila has very low opinion of Kalonzo and can barely hide his disdain.
Now he is stuck - rejoin Azimio or run alone or join Ruto.
If I was him first I would collect money from Azimio - they surely owe him

- use it to run for alone - and enter secret deal with both sides - so win or lose - he will be in gov.
It likely we will have run-off sparked by legal challenge if supreme court is led by idiots by Martha & Njoki. That will give him opportunity to make a serious deal where his premium will be sky roof.
