After being named the Opposition candidate, NASA flag bearer Raila Odinga has rapidly gained ground in the Rift Valley.
A Radio Africa poll shows his ratings have been going up, steadily eating into President Uhuru Kenyatta's grip in the vote-rich region.
The latest statistics demonstrate effects of the onslaught Bomet Governor Isaac Rutto has launched in the region since he joined the National Super Alliance as a member of Pentagon.
Other members of the coalition are Kalonzo Musyoka of Wiper, Musalia Mudavadi (Amani National Congress), and Moses Wetang'ula of Ford Kenya. Raila is ODM leader.
If elections were held today, Raila would get 28 per cent and President Uhuru Kenyatta 71 per cent in Bomet.
