Members of County Assembly (MCAs) by Ward

There are 6 administrative wards in Ainamoi. The area has been a complete UDA Party Stronghold for all elective civic positions, sweeping all positions during the 2022 election cycle.

This pattern shows that Ainamoi voters are highly responsive to national party strength and unity. When a party is popular and well-organized at the national level, local support becomes nearly total, as seen in the UDA landslide of 2022. Internal divisions, however, quickly weaken that hold, allowing challengers to gain ground, as happened in 2017.

Economy and Infrastructure

The constituency functions as a stronghold for whichever party currently dominates the South Rift, making local outcomes a clear reflection of broader political waves rather than purely local issues.

Economic opportunities, tea prices, urban infrastructure and water supply are expected to be among the defining issues heading into the 2027 General Election.

The local economy here is mainly dependent on retail trade, transport (both boda-boda and matatu) and hospitality, as Ainamoi is the Urban Real Estate and Commercial Hub. 

The heavy urbanization puts a lot of pressure on water supply, and the county has embarked on a water supply expansion project through the Kericho Water and Sanitation Company (KEWASCO).

The main economic challenge in the constituency is the high proportion of smallholder farmers who sell tea leaves to the Kenya Tea Development Agency (KTDA) factories, which large tea multinational farms surround. 

A tea export tax of 0.8% was imposed on exports, which took effect on May 1, 2026. Ainamoi’s smallholders joined urban market traders in strongly protesting the tax. Kenya Tea Development Agency (KTDA) Chairman Enos Njeru has attributed this to a drop in the tea market.
