Divisions have emerged among Nasa candidates in Narok pitting members of ODM and Chama Cha Mashinani.
The leaders have accused CCM leader Issac Ruto of abetting absenteeism.
Narok ODM governorship candidate Joseph Tiampati ole Musuni and Narok North MP Moitalel ole Kenta singled out Nasa co-principal Ruto as biased.
The group has now called wants ODM leader and Nasa flag bearer Raila Odinga to come out and equally support his party’s candidates.
“We witnessed this during the recent tour of the region by the Nasa leaders,” Mr Musuni said.
“Mr Ruto has been providing resources and support for CCM Narok governorship candidate Patrick Ntutu and has been asking people to vote for him.”
Nasa principals should let the electorate take their pick among the Nasa candidates, Mr Musuni said, and added: “Mr Ruto should be neutral, just like Mr Odinga, who, despite being the flagbearer, has remained silent.”
