KISII moved from 84.0% turnout in 2013 to 63.92% in 2022. That trend can shape 2027.
When people ask where 2027 may be won, the answer is usually simple: in counties where turnout changes fast. In KISII, turnout was 84.0% in 2013, 73.84% in 2017, and 63.92% in 2022. This is not just history. It is campaign direction.
The 2022 winner in KISII was Raila Odinga with about 65.80% of valid votes. The margin was 129,752 votes. A margin that size can hold if turnout is stable, or collapse if turnout moves by even 3-5 points in key wards.
Turnout Story: Three Elections, One Pattern
Registration in KISII has moved from 413,161 voters in 2013 to 637,111 in 2022. That is growth of 223,950 voters. But registration only matters when people actually vote, and turnout has changed by -20.08 points across that period.
Who Turned Out in 2022
The split between the two main 2022 blocs was clear in KISII. William Ruto received 135,326 votes while Raila Odinga received 265,078. This profile helps campaigns decide where to defend, where to persuade, and where to intensify get-out-the-vote work.
For context, IEBC's official results portal and reports remain the benchmark source for county tallies, while legal outcomes can be tracked through IEBC and Kenya Law. Broader demographic context is available through KNBS.
