TRANS NZOIA moved from 82.0% turnout in 2013 to 63.37% 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 TRANS NZOIA, turnout was 82.0% in 2013, 72.92% in 2017, and 63.37% in 2022. This is not just history. It is campaign direction.
The 2022 winner in TRANS NZOIA was Raila Odinga with about 52.87% of valid votes. The margin was 15,664 votes. A margin that size can hold if turnout is stable, or collapse if turnout moves by even 3-5 points in key wards.
