Rarieda MP Nicholas Gunbo has asked the ODM party not to endorse some party members in the guise they are more loyal to the party.
Gumbo said voters should allowed to exercise their democratic right by electing leaders they want.
"People who bring down institutions have been getting into leadership through party endorsements and that has left many Kenyans facing poverty, even in the era of devolution. Corrupt leaders live like Kings," Gumbo said.
He made the remarks during a funds drive for women groups at Bar-Kalare Primary School in Gem constituency on Friday.
"Every contestant must be given a chance to compete and the electorate should have the opportunity to vet candidates," he added.
There have been calls within the Orange party that the political outfit gives loyal members direct nomination.
The call led by Kisumu Governor Jack Ranguma has not, however, been received well by some party members.
"There should be no canvassing for county posts," Gumbo said.
"I will replicate my good performance in Rarieda constituency in the entire county. My bid for Siaya governor is unstoppable. The noise from my critics won’t scare me."
Gumbo is eyeing the Siaya Governor seat currently held by Cornel Rasanga.
