I believe the President will keep his promise to support William Ruto in 2022 because he vowed to do so. You will note that the relationship between the President and his DP has always been cordial. There has been no time since Jubilee came to power in 2013 that they contradicted each other.
There are select instances, like the case of lifestyle audit and war on graft, where some say the two have clashing views. But we can all remember the DP said in Mombasa that he was ready for the audit. It is just that one of our members, Kipchumba Murkomen, contradicted the President, but Murkomen is not the DP.
