What could have compelled a devoted fan base to inflict such a painful blow on a man who had provided such a diverse array of development to his home base? For the foreseeable future, this will be a major topic of discussion among political observers and historians of Kenya.
In Mt Kenya, his party, Jubilee, and the entire Azimio la Umoja Alliance did not achieve any notable electoral victories. As opposed to 2013 and 2017, today Jubilee has only five MPs and no senator from Meru, Tharaka Nithi, Embu, Kirinyaga, Kiambu, Murang'a, Nyeri, Nyandarua, Nakuru to Laikipia.
The party MPs are Dan Kiili in Igembe Central and Dr Shadrack Mwiti in South Imenti constituencies of Meru; David Kiiraho (Ol Kalau) and Kwenya Thuku (Kinangop) in Nyandarua county and Irene Njoki in Bahati, Nakuru.
Even those who won did so by the slimmest of margins, propelled primarily by sibling rivalry in President William Ruto's house - the Kenya Kwanza Alliance (KKA) .
Of course, the former president's party controls no county government, and its MCA count in the region is less than two dozen. Jubilee is not even the Minority Party in any county assembly in this region.
Kiambu, the president's home county, has no Jubilee MP. Not even in Gatundu South, where his umbilical cord is said to be buried.
Raila Odinga, the Azimio presidential candidate, received approximately 850,000 votes, which is unprecedented for him, but it remains a tickle when you consider that he had the backing of the outgoing regional kingpin.
What happened?
Many blame Uhuru, and just as many blame Ruto's scorched-earth campaigns.

"They felt Uhuru wanted to leave them in the morally precarious position of a community that negates its word," the Ruto ally said in an interview.
No kingpin left
"There was also speculation that Uhuru was a little self-centred. He failed to develop a kingpin by purposefully undercutting all potential candidates," Kang'ata said.
"Many people thought it was foolish to drag Kikuyu into an agreement with a region that had been at odds with the region, especially without a kingpin."

The former senator had a love-hate relationship with Uhuru at the end of his term, initially benefiting from Uhuru's rout of Ruto allies, then a spectacular fallout after he penned a letter informing the president of BBI's unpopularity.
Ndiritu Muriithi, an economist and former governor of Laikipia, provides snippets of what went wrong in a scientific context.
Kenyans, he said, were angry and disillusioned by the stagnation or worsening of their situation.
"Welfare is deteriorating even as top-line GDP is increasing, and access to financial services is at an all-time high of 84 per cent of adults," Muriithi said.
"They may see beautiful roads, but the percentage of Kenyans who are financially insecure has more than doubled in the last five years, from 15 per cent to 39 per cent, according to the Financial Access report by CBK, KNBS, and FSD Kenya."

According to the former governor, struggling means that people are sometimes without food and medicine and thus cannot save for emergencies or invest for the future.
"Median income has declined from Sh6,500 per month in 2016 to Sh5,000 today. Kenyans are angry at the government generally. There was rioting and looting in Eldoret this week."
According to Kikuyu Council of Elders chairman Wachira Kiago, the Ruto camp has created a fertile ground for sowing seeds of revolt against the outgoing leader.
"The truth is that Uhuru had delivered for the nation and his region but there was a lot of propaganda and outright lies. He was condemned on any imaginable ground and it seemed true because he was the one in power," said Kiago.
The elder sympathises with Uhuru, saying he did well considering he had to deal with a new constitutional order, the Covid-19 pandemic, the international financial meltdown, and the Dr Ruto-led rebellion.
Kiago added that because the population was feeling the economic sting, it was simple for Dr Ruto to de-campaign his boss.
He mentioned an effort by Kikuyu elders to bring Uhuru and deputy president Rigathi Gachagua together, saying it boded well for the future to have the two on the same side.
"The biggest mistake for the mountain will be seeking to disregard Uhuru's place in our history," warned Kiago.
Some key members of Kenya Kwanza in Mt Kenya, such as Senate Deputy Speaker Kathuri Murungi (Meru), have attributed the success of their campaign to Dr Ruto's permanent presence there for 10 years.
"He has been deep into villages in every constituency conducting harambees and identifying local problems. He was the familiar option and the people remembered it," Murungi said in a past interview.
Federation of Evangelical and Indigenous Churches of Kenya chairman Bishop Samuel Njiriri said Dr Ruto worked for his victory, citing his passionate courting of the Church.
