Nandi and Uasin Gishu: Inside UDA's Two Fortress Counties

Nandi gave William Ruto 94.56% of the presidential vote. Uasin Gishu gave him 85.32%. Together, these two Kalenjin heartland counties produced a combined net margin of approximately 390,000 votes — more than Ruto's entire national winning margin of 233,211.

These are not counties where politics is competitive. They are counties where opposition is a foreign concept — where Ruto's dominance is so complete that rival candidates barely campaign. The question isn't whether Ruto will win Nandi and Uasin Gishu, but by how much.

Nandi County: 94.56% — The Purest UDA Territory

The Numbers:

• Registered voters: 393,889
• William Ruto: 254,117 votes (94.56%)
• Raila Odinga: 12,441 votes (4.63%)
• Others: 2,178 votes (0.81%)
• Turnout: 68.20%
• Net Ruto margin: 241,676

Nandi's 94.56% for Ruto was one of the three highest vote shares in the entire country, rivalled only by Homa Bay's 97.06% for Odinga and Elgeyo Marakwet's 96.86% for Ruto. But unlike those counties, Nandi combined a very high vote share with above-average turnout (68.20% vs. national 64.77%). This combination of loyalty and mobilisation made Nandi pound-for-pound one of the most productive counties in Ruto's coalition.

Nandi is overwhelmingly Nandi Kalenjin — one of the sub-groups within the larger Kalenjin community. Ruto, while from the Tugen sub-group (from Baringo), commands near-total Kalenjin loyalty. The community's political unity has been a feature of Rift Valley politics since the Moi era, and Ruto has inherited and deepened it.

Uasin Gishu County: The Capital of Ruto Country

The Numbers:

• Registered voters: 510,853
• William Ruto: 293,281 votes (85.32%)
• Raila Odinga: 47,299 votes (13.76%)
• Others: 3,145 votes (0.92%)
• Turnout: 67.43%
• Net Ruto margin: 245,982

Uasin Gishu is where Ruto lives. His home in Sugoi is in Moiben constituency. Eldoret, the county seat, is Kenya's fifth-largest city and the de facto capital of Kalenjin politics. The county has a more diverse population than Nandi — including significant Kikuyu, Luhya, and other communities in Eldoret town — which explains why Ruto's share (85.32%) is lower than Nandi's near-total unanimity.

The 13.76% for Odinga in Uasin Gishu likely reflects the non-Kalenjin urban population of Eldoret. In Eldoret North and Eldoret South constituencies, Odinga's share was estimated at 18-22%, driven by Luo, Luhya, and Kisii residents of the city. In rural constituencies like Moiben, Kesses, and Soy, Ruto's share exceeded 90%.

Historical Voting: These Counties Never Waver

The Rift Valley Kalenjin vote has been remarkably consistent across elections:

• 2002: Backed Uhuru Kenyatta (KANU) — Moi's chosen successor. Nandi ~80% for Kenyatta, Uasin Gishu similar.
• 2007: Backed Raila Odinga (ODM) — the anti-Kibaki coalition. Nandi ~95% for Odinga, Uasin Gishu ~90%.
• 2013: Backed Uhuru Kenyatta (Jubilee) — the Kenyatta-Ruto alliance. Nandi ~95% for Kenyatta, Uasin Gishu ~85%.
• 2017: Same pattern as 2013.
• 2022: Backed William Ruto (UDA) — now as the principal, not deputy.

The pattern shows that the Kalenjin vote follows community leadership with extraordinary discipline. When Moi endorsed Kenyatta in 2002, the community followed. When the community rallied behind Odinga in 2007, the vote was near-unanimous. And when Ruto became the standard-bearer in 2022, the result was predictable.

The key insight: these counties don't vote for a party. They vote for their leader. UDA could be replaced by any party — what matters is that Ruto is on the ticket.

The Turnout Advantage

What separates Nandi and Uasin Gishu from Odinga's fortress counties (Kisumu, Homa Bay, Siaya) is turnout. While Odinga's strongholds delivered 93-97% vote shares, their turnout was 50-56%. Nandi's 68.20% and Uasin Gishu's 67.43% turnout meant they produced more absolute net votes per registered voter.

Here's the comparison:

• Nandi: 393,889 registered × 68.20% turnout × 94.56% Ruto = 254,117 Ruto votes. Net margin: 241,676
• Siaya: 479,078 registered × 49.67% turnout × 96.32% Odinga = 226,777 Odinga votes. Net margin: 219,751

Nandi, with 86,000 fewer registered voters than Siaya, produced a larger net margin — entirely because of superior turnout. This is the arithmetic that determines elections. Vote share grabs headlines; turnout wins races.

Can Anything Change in 2027?

Short answer: almost certainly not. Ruto will carry Nandi and Uasin Gishu in 2027 with margins similar to 2022. The only scenarios that could alter this:

1. A Kalenjin rival: If a credible Kalenjin politician challenged Ruto — deeply unlikely given the community's unity culture — some votes could split. There is no such candidate on the horizon.
2. Turnout suppression: If Ruto supporters feel comfortable enough to stay home ("he'll win anyway"), turnout could drop, reducing his net margin. This happened with Uhuru's supporters in 2017.
3. Demographic change: Eldoret's rapid urbanisation is bringing more non-Kalenjin residents into Uasin Gishu. Over time, this could erode the 85% ceiling. But not by 2027.

For the opposition, the lesson is simple: don't waste resources trying to compete in Nandi and Uasin Gishu. Instead, focus on matching their turnout in your own strongholds. If Nyanza had turned out at 68% instead of 52%, the 2022 election would have been a dead heat.
