Former Interior CS Joseph ole Lenku has clinched Jubilee's ticket for the Kajiado governor seat.
Lenku garnered 18,456 votes in party primaries on Wednesday, while his rival Tarayia ole Kores received 6,705 votes.
The former CS's bid had been criticised by incumbent Governor David Nkedianye.
But Lenku may prove critics wrong, having secured himself a place on the August 8 ballot.
The primaries saw notable politicians, including Kajiado West MP Moses Sakuda, lose out.
Most of those voted said they wanted to make a statement to those still abusing their political office who "thought they are untouchable".
“This is a strong statement to those who have always thought they are the bosses of the voters,” said Taiko Lemayian in Kajiado town.
