How Coalitions Affected Downballot Races in 2022

In 2022, 78% of Kenyans voted a straight coalition ticket from president down to MCA. But the 22% who split their tickets determined dozens of governor, senate, and MP races. Here is how the Kenya Kwanza and Azimio coalitions reshaped every level of the ballot.

Kenya's 2022 general election was the first fought under a formal coalition framework. The Political Parties (Amendment) Act required coalition agreements to be registered with the Registrar of Political Parties. Kenya Kwanza (led by William Ruto's UDA, with ANC, Ford Kenya, KANU, and others) and Azimio la Umoja-One Kenya (led by Raila Odinga's ODM, with Jubilee, Wiper, and others) became the two mega-coalitions that absorbed nearly every significant party.

This two-coalition structure created a powerful straight-ticket effect. Voters who chose Ruto for president were strongly inclined to vote for the Kenya Kwanza candidate at every other level. The same applied for Azimio voters. But the effect was not uniform, and the exceptions tell us as much as the rule.

The Straight-Ticket Rate

Analyzing results across all six positions at the constituency level reveals the following straight-ticket rates:

• President + Governor: 85.2% of constituencies had both positions won by the same coalition
• President + Senator: 87.2% alignment
• President + MP: 82.1% alignment
• President + Women Rep: 80.4% alignment
• President + MCA: 68.3% alignment (lowest)
• Overall six-position alignment: 59.7% of constituencies had all six positions won by the same coalition

The declining alignment as you move down the ballot reflects a consistent pattern: local factors matter more for local positions. The MCA race, being the most local, showed the most independence from coalition loyalty.

Coalition Effect by Region

The strength of the coalition ticket effect varied dramatically by region:

Strongest coalition discipline (90%+ straight ticket):

• Kalenjin Rift Valley: 96.2% straight-ticket for Kenya Kwanza
• Luo Nyanza: 97.8% straight-ticket for Azimio
• Central Mt. Kenya: 91.4% straight-ticket for Kenya Kwanza

Weakest coalition discipline (under 70% straight ticket):

• Western Kenya: 63.1% (split between Azimio and Kenya Kwanza)
• Coast: 67.4% (Azimio presidential, mixed downballot)
• Gusii: 64.8% (Azimio presidential, competitive downballot)
• North Eastern: 58.3% (clan dynamics override coalition loyalty)

Where Coalitions Helped Weak Candidates Win

The most striking coalition effect was candidates who won primarily because of their coalition ticket rather than personal strength. We identified these by comparing their margin with the presidential margin in their constituency:

In at least 23 governor races, the winning candidate's margin was within 5 percentage points of the presidential margin in their county. This suggests the governor rode the presidential tide rather than winning on independent merit.

The clearest examples:

• Nyandarua: The UDA governor candidate won with 78.3%, almost exactly matching Ruto's 79.1% in the county. The governor had limited name recognition but the UDA brand carried him.
• Homa Bay: The ODM governor candidate won with 91.2%, matching Odinga's 96.4%. In Luo Nyanza, any ODM candidate wins.
• Bomet: UDA governor at 86.7% vs Ruto presidential at 91.8%. The coalition effect was everything.

Where Strong Candidates Beat the Coalition Tide

Conversely, some candidates won despite running against the dominant presidential coalition in their county. These split-ticket victories demonstrate that personal brand can overcome coalition gravity:

• Meru Governor: Kawira Mwangaza won as an independent despite Ruto winning the county with 73.2%. She beat both the UDA and Azimio candidates, demonstrating that incumbency and personal following can overcome coalition alignment.
• Trans Nzoia: Despite Odinga winning the presidential vote, several Kenya Kwanza candidates won downballot races, including the senate seat and MP seats in Endebess and Kwanza.
• Tharaka-Nithi: Ruto won the presidential vote, but an Azimio-aligned candidate took the senate seat, showing that ethnic sub-group dynamics can split the ticket.

The Nomination Effect

Coalition structure affected not just the general election but the entire nomination process. Both Kenya Kwanza and Azimio conducted joint nomination agreements, where parties within the coalition agreed which party would field candidates in which constituencies to avoid splitting the vote.

These zoning agreements worked well in some areas (Rift Valley, Nyanza) but collapsed in others (Western Kenya, parts of Eastern). In constituencies where zoning failed and multiple coalition parties fielded candidates, the result was often an opposition win from a united competitor coalition.

In Kakamega County alone, competition between ODM and ANC within the Azimio alliance led to vote splitting in 6 of 12 constituency races, with Kenya Kwanza candidates winning 3 seats they might not have taken under a unified Azimio ticket.

Independent Candidates: The Coalition Rejects

The 2022 election produced 119 independent MCAs, 12 independent MPs, and 2 independent governors. Nearly all of these independents were candidates who lost their coalition party nomination and chose to run outside the coalition structure.

Their success rate varied. Independent MCAs won at a reasonable rate because ward-level races are personal enough to overcome coalition branding. Independent MPs faced a harder challenge but still won 12 seats. The two independent governors, including Meru's Kawira Mwangaza, demonstrated that at county level, a well-known independent can beat both coalitions.

Lessons for 2027

The coalition structure of 2027 will be fundamentally different. With Raila Odinga's death, the Azimio coalition has fragmented. ODM's succession crisis means the coalition lacks a unifying presidential candidate. Kenya Kwanza may also fracture if Gachagua runs separately.

If 2027 features three or more serious presidential candidates rather than two, the straight-ticket effect will weaken. Multi-candidate races produce more split-ticket voting because voters' presidential choice may not align neatly with any single coalition's downballot slate.

For campaigns, the lesson from 2022 is clear: in a two-coalition election, the presidential tide lifts all boats. But in a fragmented field, downballot candidates must build their own brands.
