Anne Waiguru is ahead of Martha Karua in the Kirinyaga gubernatorial race with 20 percentage points, the latest TIFA poll shows.
The poll released on Thursday in Nairobi shows Ms Waiguru has 55 per cent approval rating against Ms Karua’s 35 per cent.
Ms Waiguru’s popularity seems to be linked to the popularity Jubilee Party enjoys in the county.
The Uhuru Kenyatta party enjoys 95 per cent support while Ms Karua’s Narc-Kenya has a paltry two percent.
The incumbent, Joseph Ndathi, who is defending his seat as an independent, has a paltry three per cent support, according to the survey.
Some seven per cent of Kirinyaga voters are undecided but it is unlikely that their number will change the current ratings.
Some 556 respondents took part in the Kirinyaga survey that had a +/-4.4 percent error margin.
The poll was conducted through face-to-face interviews between July 14 and July 17.
