Governor Sakaja vs Igathe: The Most Expensive City Campaign in Kenyan History

Over KES 4 billion was spent by the two Nairobi governor campaigns combined. Sakaja won with 53.8% but the real story is how money, controversy, and coalition politics shaped the most watched county race in Kenya.

Nairobi is not just Kenya's capital. It is the country's largest economy, the seat of government, and the most visible political arena in East Africa. When Kenyans went to vote on 9th August 2022, the Nairobi governor race commanded national attention rivalled only by the presidential contest itself.

Johnson Sakaja, running on the Kenya Kwanza ticket, defeated Polycarp Igathe of the Azimio la Umoja coalition by 699,392 votes (53.78%) to 574,710 (44.19%). The margin was 124,682 votes, a comfortable win by county standards but one that masks a bitter, controversial, and extraordinarily expensive campaign.

The Numbers That Define the Race

Nairobi had 2,442,856 registered voters in 2022, the largest electorate of any county. Turnout was 54.63%, the second-lowest county turnout in the country after Mombasa. That means 1.1 million registered Nairobi voters stayed home, more than the entire registered voter population of most counties.

The total valid votes for governor were 1,300,281. There were nine candidates, but only Sakaja and Igathe were competitive. The remaining seven shared just 26,179 votes between them, or 2% of the total.

Rejected ballots numbered 34,180, representing 2.56% of total ballots cast for governor. This was notably higher than the presidential rejection rate of 0.80%. Nairobi's governor ballot had more candidates and a more complex layout, contributing to voter error.

Campaign Spending: The KES 4 Billion Race

Kenya's campaign finance laws nominally cap governor spending at KES 431 million per candidate, based on the IEBC formula of KES 35 per registered voter multiplied by relevant factors. In practice, enforcement is virtually non-existent.

Media monitoring by the Kenya Editors Guild documented over KES 800 million in advertising spend by each campaign across television, radio, print, and digital platforms. Both campaigns ran extensive ground operations involving thousands of paid agents per constituency. Political analysts at the University of Nairobi estimated total campaign expenditure at between KES 3.5 and 4.5 billion when factoring in transport, events, merchandise, and what Kenyans euphemistically call facilitation.

For context, this is more than the annual budget allocation for several of Kenya's smaller counties. The Nairobi governor race alone likely cost more than the combined governor campaigns in the 20 smallest counties.

The Degree Controversy

Sakaja's candidacy almost ended before it began. In June 2022, questions arose about the authenticity of his degree from Team University in Uganda. The Commission for University Education (CUE) initially found the degree irregular. The case went to court, and ultimately the Milimani High Court cleared Sakaja to run, ruling that the IEBC had already verified his qualifications during the nomination period.

The degree saga dominated media coverage for three weeks, effectively freezing Sakaja's campaign momentum. Polls showed Igathe pulling ahead during the controversy. But Sakaja's team turned the narrative around by framing it as a political attack, and his numbers recovered once the court cleared him.

Igathe, by contrast, had impeccable academic credentials: a degree from the University of Nairobi and an MBA from USIU. He had also served as Nairobi deputy governor under Mike Sonko before resigning in January 2018, citing an inability to work with Sonko. That resignation gave him both credibility (he was principled enough to quit) and a question mark (could he handle the rough-and-tumble of Nairobi politics?).

Constituency-Level Results

Sakaja won 12 of Nairobi's 17 constituencies. His strongest performance was in Kasarani (61.2%), Lang'ata (58.7%), and Westlands (57.3%). Igathe won five constituencies: Kibra (68.4%), Mathare (54.1%), Kamukunji (52.8%), Starehe (51.3%), and Embakasi Central (50.7%).

The pattern largely mirrored the presidential vote. Areas where Ruto performed strongly also went for Sakaja. The coalition ticket effect was powerful: Kenya Kwanza voters in Nairobi typically voted straight-ticket from president down to MCA.

The exception was Lang'ata, where Sakaja outperformed Ruto by about 4 percentage points. This is significant because Lang'ata includes Karen and other upper-middle-class areas where Sakaja's personal brand as a young, educated senator played well. He was the local choice regardless of coalition.

What Made Sakaja Win

Three factors explain Sakaja's victory:

1. The coalition effect. Kenya Kwanza's presidential campaign machinery in Nairobi directly benefited Sakaja. The party invested heavily in Nairobi because the presidential race there was competitive, and downballot candidates rode the wave.
2. The young urban brand. At 37, Sakaja was the youngest serious candidate. His social media presence, lifestyle branding, and use of Sheng in campaign messaging resonated with Nairobi's young demographic. Over 40% of Nairobi's registered voters are under 35.
3. Igathe's outsider perception. Despite being born in Nairobi and having served as deputy governor, Igathe was branded as a corporate executive parachuted into politics. His resignation from the deputy governor role was used against him: if he quit once, would he quit again?

The Cost-Per-Vote Analysis

If campaign spending was indeed in the KES 4 billion range (combined), and total valid votes were 1.3 million, the cost per vote was approximately KES 3,077. For Sakaja alone, assuming he spent about KES 2 billion, each of his 699,392 votes cost roughly KES 2,860.

Compare this to the 2022 Kiambu governor race, where Kimani Wamatangi won in a county with similar registration numbers but where total campaign spending was estimated at under KES 1 billion combined. Nairobi's governor race was at least four times more expensive per vote than Kiambu's.

The financial barrier this creates for future candidates is significant. To credibly contest the Nairobi governorship, a candidate now needs access to at least KES 1.5 billion. This effectively limits the field to the wealthy, the party-backed, or the coalition-supported.

What This Means for 2027

Sakaja is a first-term governor and can run again in 2027. His record in office, particularly on the Nairobi expressway revenue sharing, garbage collection, and matatu regulations, will determine whether he faces a serious challenge.

For Azimio, the question is whether they can find a candidate who combines Igathe's competence with grassroots appeal. With Raila Odinga's passing in October 2025, the Azimio coalition has fragmented, and Nairobi's opposition politics lacks a unifying figure.

The deeper question is turnout. Nairobi's 54.63% turnout means 1.1 million votes are on the table. Any candidate who can mobilize even half of those non-voters changes the math entirely.
