OAKLAND -- Steve Manning won the race to be the next Alameda County auditor-controller with about 74 percent of the countywide vote Tuesday, earning a promotion from his longtime job as deputy chief auditor.

His opponent, Kathleen Knox, pulled in more than a quarter of the votes despite dropping out of the race after her arrest a month ago on six felony fraud charges. Knox has pleaded not guilty to charges of lying about her residency to run for office and vote in an Alameda County election.

Poll workers on Wednesday still had more than 64,000 absentee votes to count but have already reported more than 76,000 votes for Manning and about 26,400 for Knox.

Turnout in the election was low, about 25 percent of all registered voters in Alameda County.

Manning, who has worked in the auditor's office for 27 years, will replace Alameda County Auditor-Controller/Clerk-Recorder Patrick O'Connell, who plans to retire at the end of the year after holding the seat since the late 1980s.

Knox, owner of a senior care home business, promised to root out waste and fraud but admitted to this newspaper in April that she did not live in the San Leandro residential care home she listed as her home address on voting and candidacy papers. She was later arrested at a house she owns in Danville. She announced her withdrawal from the race in mid-May, after her name was already on ballots mailed to voters. She awaits a preliminary court hearing this summer.

Also securing seats in Alameda County on Tuesday were several incumbent officials whose elections were uncontested.

Alameda County Sheriff-Coroner Greg Ahern, District Attorney Nancy O'Malley, Assessor Ron Thomsen, Treasurer-Tax Collector Donald White and Supervisors Richard Valle and Wilma Chan will all keep their jobs for another four years. The seats of three other supervisors will be up for re-election in 2016.
