Lamu County Assembly Speaker Abdul Kassim is hoping to retain his position against stiff competition from six rivals.
Kassim's competitors include nominated MCA Salim Al Busaidy, who has accused the second county assembly of failing in its role to oversight the executive.
Al Busaidy said he was coming in to change the way things are done.
"Lamu is in dire need of a vibrant county assembly that legislates and at the same time keeps the county executive in check. Unfortunately, this did not happen during the second county assembly," he said on Wednesday.
Kassim finished a distant third in Lamu West parliamentary race.
Al Busaidy, a confidant of the incoming governor Issa Timamy, is considered a favourite to clinch the seat.
Trade and Tourism Chief Officer Atwaa Salim is also eyeing the seat, and so is Shela Ward MCA Azhar Mbarak, who has clinched the ward seat for the third time.
Julius Ndegwa, a former Lamu West MP and Safina Party deputy governor candidate in this year's elections, and former Lamu senator Anwar Loitiptip have also expressed interest in the position.
Former county assembly clerk Zachary Mboche, who unsuccessfully contested Lamu West parliamentary seat, is also gunning for the speaker's position.
During his campaigns, Mboche indicated he would seek the speaker's post if he missed the parliamentary seat.
Also jostling for the seat is Ruth Wambui who unsuccessfully vied for the Nyandarua Woman representative seat.
Meanwhile, most MCAs in Kilifi and Tana River counties failed to retain their seats during the elections. Poor performance has been cited as the main reason voters rejected them.
In Kilifi, some residents said the former MCAs failed in their oversight role, exposing the county to rampant corruption and general mismanagement of resources by the executive.
Each of the 35 wards gets Sh25 million Ward Development Fund and another Sh10 million for Education Scholarship Fund. The funds are managed by the executive while MCAs act as patrons.
Some claimed bursaries were being dished out without following the laid-down procedures and the many deserving cases were denied the money.
In Tana River, county assembly speaker Michael Justin Nkaduda accused former MCAs of having been driven by the desire to get rich quickly: "They never bothered to oversight the county executive."
"I wanted to introduce live coverage of events at the assembly but they refused because they knew they were lazy and would be exposed. But I believe the new MCAs will be focused and will deliver on their mandate," he said.
