Incumbent Douglas Drewel won his Republican primary contest Tuesday in Maries County.
He had been challenged by Mike Moreland for the Republican nomination for Eastern District associate commissioner. No Democrat has filed for the office, leaving Drewel unopposed in the November general election.
Drewel garnered 531 votes, while Moreland trailed with 393.
That was the only contested courthouse office in primary balloting.
Democrat Buddy Thompson will challenge Republican incumbent Harold "Chris" Heitman for sheriff in the November election. Neither candidate faced a contest for their respective party nominations. Heitman polled 1,559 votes, while Thompson polled 331.
Three other county-level positions held by Democrats were uncontested Tuesday and also will be in November. Dana Simmons, who is pursuing her third term as assessor, had 346 votes Tuesday. Ed Fagre, who seeks to continue as Western District associate commissioner, an office he's held for 28 years, earned 198 votes. David Martin, funeral director at Birmingham-Martin Funeral Home, garnered 336 votes in his bid to continue his long-running service as county coroner.
Republican Carol Jo Schulte earned 1,562 votes pursuing a second term as public administrator, with no primary or general election challenger having filed.
