The parliamentary race in Mwingi West Constituency is steadily narrowing into a two-man showdown, according to the latest survey by Mizani Africa released on February 25, 2026.

The poll places Hon. Charles Ngusya Nguna ahead with 44.1 percent of voter preference, while Jonathan Ngenga follows at 31.8 percent. With other aspirants attracting minimal support and 17.8 percent of voters still undecided, the contest is increasingly defined not just by popularity, but by viability and momentum.
Beyond voter preference, the survey delves into Nguna’s job performance, offering a deeper look at how constituents perceive his leadership.
Residents were asked to rate his performance on a scale of one to ten, and the outcome produced a 56.9 percent approval rating. That figure signals moderate but firm backing from a majority of respondents — a critical factor for any incumbent facing a competitive challenger.

The methodology behind the findings adds weight to the numbers. Mizani Africa interviewed 581 respondents drawn from all four wards of Mwingi West, targeting a constituency with approximately 57,138 registered voters based on 2022 IEBC data. Conducted between February 16 and 19 through Computer-Assisted Telephone Interviewing, the survey carries a margin of error of plus or minus 3.9 percentage points at a 95 percent confidence level.
Within accepted polling standards, this suggests the trends captured reflect a credible snapshot of the political mood on the ground.
Demographically, the survey leaned heavily toward rural voices, with 80 percent of respondents drawn from rural settings — a significant detail in a largely rural constituency.
The sample was slightly male-dominated at 52 percent, and most participants fell within the economically active age bracket.
Nearly seven out of ten respondents were between 25 and 45 years old, underscoring that the findings are strongly shaped by the working-age population. Educational backgrounds varied, though most respondents had either primary or secondary education, with smaller proportions holding college or university qualifications.
Taken together, the data suggests that Nguna’s performance resonates particularly with the rural, working-age demographic that forms the backbone of the constituency’s electorate. However, the sizeable undecided bloc remains the race’s most unpredictable element.
In tightly contested seats, such voters often become the ultimate kingmakers, influenced by campaign energy, development narratives, coalition alignments and local trust.
For now, Mwingi West appears headed toward a direct contest between Nguna and Ngenga. While the incumbent holds both a preference lead and a majority approval rating, the gap is not insurmountable.
As the campaign season gathers momentum, the race will likely hinge on consolidation, persuasion and the ability to convert approval into actual votes at the ballot.
The political temperature in Mwingi West is rising — and if the current trends hold, voters may soon witness one of the most closely watched parliamentary duels in Kitui County.
