Clark County Clerk Sherry Parker is locked in a tight race with Republican challenger Scott Weber.Preliminary results showed Parker with 49.98 percent of the votes and Weber with 49.90 percent.Parker, a Democrat trying for a second term, received 84 more votes than Weber, according to preliminary figures released at 8:15 p.m. Tuesday.Weber, 38, a manufacturing engineering technician for Columbia Machine, won 51 percent in August’s primary.Parker, 63, attributed that loss to low turnout of Democrats. During the campaign, Weber said he became interested in the clerk’s office in 2006 because he was annoyed by Parker’s yellow diamond-shaped campaign signs. So he looked into the job, which includes serving as the Superior Court’s financial officer and keeper of the records.Weber advocates changing the clerk’s position from elected to appointed, which would require voters to adopt a home-rule charter. Auditor Greg Kimsey, who oversees elections, said Tuesday there are between 30,000 and 35,000 ballots to be counted. An updated count will be released at approximately 5 p.m. today, Kimsey said.Traditionally, late ballots have trended conservative, he said.In a race for assessor that pitted outsider Peter Van Nortwick versus insider Janet Seekins, voters appeared to favor the outsider. Tuesday’s preliminary results showed Van Nortwick with 51.3 percent of the vote.He was 2,833 votes ahead of Seekins.Van Nortwick said Tuesday he’s “cautiously optimistic” that he’ll hang on to the lead.Van Nortwick, 43, a self-employed appraiser, kicked off his campaign well before filing week with criticism of Assessor Linda Franklin, who decided not to seek a third term. Van Nortwick argued the county unfairly assesses properties, leading to some people paying too much in property taxes while others pay too little. Seekins, 53, has worked for the assessor’s office for 29 years. She told voters that Van Nortwick doesn’t understand how to do mass appraisals and defended the county’s average of assessing property at 92 percent of market value, above the state average of 87 percent.In other county races, Sheriff Garry Lucas easily won a new four-year term. Preliminary results showed Lucas, 67, with 60 percent of the vote to Timothy Shotwell’s 40 percent. Lucas, a Republican first elected in 1990, also defeated Shotwell, a Democrat who is president of the jail custody officers’ guild, four years ago. Clark County Treasurer Doug Lasher, 61, will return to office for an eighth term, as preliminary results showed the Democrat with 55 percent of the vote.
