Cheruiyot who is in his early 30s garnered 17,565 votes to secure the ticket ahead of seasoned politicians Sammy Chepkwony with 17,081 votes, former Roads Minister Franklin Bett who came in third with 16,914 votes while former ODM Executive Director and former Kipkelion MP Margerer Langat had 14,059 votes.
The exercise had attracted six contestants who conceded defeat and vowed to campaign for the winner.
The JAP candidate will now face off with former Cabinet Minister and Bureti MP Paul Sang who is being fronted jointly by KANU and Bomet Governor Isaac Ruto’s Mashinani Development Party of Kenya (MDPK).
Raila Odinga’s ODM also declared it would support the candidate fronted by the parties which have some political base in the North Rift.
Sang, in the March 4, 2013 polls, came second after United Republican Party (URP)’s Charles Keter who is now Energy Cabinet Secretary.
The Kericho Senate by-election was called after Keter quit the seat to take up his appointment in the Cabinet overseeing the Energy and Petroleum portfolio.
