He did long time ago. He just have to fulfil his end of Handshake bargain.
When you see his drunkmate Muturi and Cousin Kungu actively supporting and campaigning for Ruto know its wrap.
You can even sense how weak Railas 2022 candidature is and thats why you have turned it to be a battle between Ruto and Uhuru.
So boring it is for you that you attack Ruto supporters trying to make it a competition of who gives Ruto more support.
Handshake finished both Raila and Uhuru . A disaster for Raila as the last 3 campaigns he had built them around Anti GEMA hate which had made him the face of Anti GEMA .
So uhuru has accepted his fate.
