2022 County Spotlight: Trans Nzoia — Where East Met West

Trans Nzoia sits at the precise geographic and political boundary between Western Kenya and the Rift Valley. In 2022, it lived up to its crossroads position: Odinga won 52.87% against Ruto’s 46.61%. The margin was just 15,664 votes — a gap of 6.26 percentage points. Out of 47 counties, Trans Nzoia was one of the most competitive. This is what a genuine battleground looks like.

With 399,230 registered voters and a diverse population of Bukusu (Luhya), Sabaot (Kalenjin), Kikuyu, and other communities, Trans Nzoia’s elections are decided by which coalition best mobilises its base and persuades swing voters.

The 2022 Presidential Result

• Raila Odinga (Azimio): 132,440 votes (52.87%)
• William Ruto (UDA): 116,776 votes (46.61%)
• George Wajackoyah (Roots): 883 votes (0.35%)
• David Mwaure (Agano): 414 votes (0.17%)
• Total valid votes: 250,513
• Rejected ballots: 2,470
• Registered voters: 399,230
• Turnout: 63.37%

With a margin of 15,664 votes, Trans Nzoia is the kind of county where a well-executed GOTV operation in two or three wards can flip the result. The rejected ballot count of 2,470 (0.98% of ballots cast) is also significant — if those ballots were valid and split at the county’s overall ratio, they would have added approximately 1,305 to Odinga’s tally and 1,150 to Ruto’s.

2017 vs 2022: A Political Reversal

Trans Nzoia’s 2022 result represents a notable shift from 2017:

• 2017: Odinga 134,312 (54.22%), Kenyatta 110,489 (44.60%)
• 2022: Odinga 132,440 (52.87%), Ruto 116,776 (46.61%)

The headline numbers look similar, but the underlying dynamics changed. Odinga’s raw vote barely moved (down 1,872), while the UDA/Jubilee vote increased by 6,287. The margin narrowed from 23,823 votes (2017) to 15,664 (2022). If the trend continues, Trans Nzoia could flip in 2027.

What drove the narrowing? Ruto’s campaign invested heavily in Trans Nzoia, targeting the Sabaot community in Mt. Elgon area and the Kalenjin minorities scattered across the county. According to Daily Nation’s reporting, local UDA candidates for governor and senator helped drive Ruto’s numbers higher through coalition ticket effects.

Trans Nzoia’s Strategic Position

Trans Nzoia’s political geography makes it a barometer for broader regional trends. It borders:

• Bungoma (west): Ruto 63.16% — a Western county that flipped to Ruto
• Kakamega (south): Odinga 71.04% — firmly Odinga
• Uasin Gishu (east): Ruto 78.00% — solidly Ruto
• West Pokot (north): Ruto 63.30% — Rift Valley lean

Trans Nzoia is literally wedged between Odinga territory (Kakamega) and Ruto territory (Uasin Gishu, Bungoma). Its result — a narrow Odinga win — perfectly reflects its position at the junction.

Turnout and the Missing Voters

Trans Nzoia’s turnout of 63.37% was below the national average of 64.77% and well below its Rift Valley neighbours (Uasin Gishu 69.51%, West Pokot 79.51%). Approximately 146,247 registered voters did not vote.

Who are these missing voters? In a county this competitive, the answer matters enormously. If the non-voters lean Odinga (as demographic estimates suggest, given the larger Bukusu population), higher turnout would widen the Odinga margin. If they lean Ruto, the county could flip.

The IEBC’s post-election report noted that Trans Nzoia had relatively good network coverage (614 of 639 stations on 3G/4G in 2017), meaning the infrastructure for digital results transmission is in place. The challenge is purely political: mobilisation.

Lessons for 2027

1. Trans Nzoia is flippable. A 6.26-point margin in a diverse county means either side can win with the right strategy.
2. The margin is narrowing. From 23,823 votes in 2017 to 15,664 in 2022. Another election cycle could close it entirely.
3. Turnout is the deciding factor. At 63.37%, there are 146,247 registered non-voters. The party that mobilises even 10% of them gains a decisive advantage.
