ODM leader Raila Odinga is the most preferred presidential candidate, an Opinion Poll by Ipsos Synovate shows.
The poll released on Tuesday showed Raila leading the race with 47 per cent followed by Deputy President William Ruto who has 41 per cent.
Roots Party leader George Wajackoyah came in a distant third with 2.9 per cent of the votes while Agano Party's David Mwaure will get 0.2 per cent.
With a margin error of +/-1.25 per cent, none of the front-runners would manage a first-round win.
However, the study conducted between 23rd - 26th July has 4 per cent undecided voters who can tilt the race.
The study had 6,105 respondents from all 47 counties.
The poll comes six days to the August 9 polls.
If elections were to be held today, the poll shows neither Raila nor Ruto, the leading presidential candidates, will garner the 50 plus one required to win the presidency.
This is the first poll to be released by Ipsos Synovate since the campaigns officially started.
