Bonny Khalwale has now thrown his weight behind DP Ruto.
He has argued that it is not possible for any other presidential aspirant to hammer Mr. William in 2022.
It is however not clear whether he has quit his party, Ford Kenya or not.
"I have long experience in Kenya's politics and I know it's not possible to defeat a government candidate in an election," the former Kakamega Senator said.
Speaking at a fundraising for the United Pentecostal Evangelistic Church in Eldoret on Sunday, he said that he was not backing DP Ruto to gain any money.
Mr. Khalwale who is also commonly referred to as "Bull fighter" said Mr. Ruto has always been on the victorious side since the 90's.
"That is why I have decided not to waste my time elsewhere," he added.
He claimed to have worked with Ruto for long and that they understand each other very well.
"Please Church leaders I urge you to pray for leaders from my Luhya community who think I am in a commercial venture by doing what I am doing", He added.
Mr. Khalwale also appealed to ANC leader Mr. Mudavadi to form an alliance with DP Ruto as his running mate.
"When Mudavadi goes to get a running mate like Jeremiah Kioni and think he will make it then it's a dream," Khalwale said.
