Thurston County Assessor Patricia Costello, a Democrat, was handily re-elected to her third, four-year term over GOP challenger Tom Crowson.
Costello, 67, of Olympia, led by almost 2 to 1 over Crowson, 54, of Olympia, a homebuilder, appraiser and former firefighter.
Crowson, also a former congressional candidate, waged a strong campaign attacking Costello's assessments appeal rate. He claimed Thurston County had one of the highest rate of appeals among comparable counties statewide.
But Costello denied Crowson's analysis, saying she had a strong record of delivering good customer service in the $85,000-a-year county job.
