Senator Moi said the DP's mission for Baringo and entire Rift Valley region is purely for his own selfish gain.
He said: "I guess every time Ruto is free with his wife he is ever singing my name Gideon, Gideon, Gideon..."
Moi said the DP's obsession is to see him voted out during the August 8 election.
"I think this forces him to sing my name even in his 'bedroom'."
Moi is facing off with former Betting and Licensing boss Simon Chelugui for the legislative seat.
"The DP simply wants me to vanish in politics so that he succeeds President Uhuru Kenyatta in 2022," he said.
He made the comments during his campaign launch at Kabimoi, Eldama-Ravine, Baringo county on Saturday.
Moi said his political nemesis frequents Baringo more than any other place in the country.
The two have been going gloves off in attacks against one another following their bid to control the Rift Valley vote.
He added that the DP pledges and channels Jubilee administration projects worth millions of shillings to Baringo.
"This is not because he loves the people here but for a simple interest to make me voted out in August," he said.
His sentiments came barely a week after Jubilee nominees in Baringo proclaimed that Kanu is dead and gone.
