Another incumbent county commissioner faces a potential challenge and a third candidate is joining the race for the one open seat on the 12-member commission in the Aug. 7 election. Only two new candidates picked up qualifying petitions last week, according to a weekly report issued by the Dickson County Election Office. Shane Nichols of Wolf Branch Road in Vanleer picked up papers to run for county commission in the 3rd District. First-term incumbent Shane Chandler of Highway 49 in Vanleer has already turned in his papers to seek another four-year term in the 3rd District. With 11 of 12 incumbent commissioners starting the process to qualify for the ballot, only the 4th District appears to be an open race as incumbent J.B. Smith has been dealing with health issues and has not picked up papers to run again. Former Commissioner Tim Harris of Maple Valley Road in Charlotte picked up, completed and turned in a qualifying petition to be on the ballot last week. Fourth District Road Commissioner Jerry Tucker of Highway 49 in Charlotte has already qualified for the ballot and Jerry Grubbs of Maple Valley Road has picked up a petition but had not returned it as of Friday. There are now potentially four opposed races for the 12-seat county commission as incumbent Kyle Sanders is challenged by Clayton Ellis in the 8th District and incumbent Linda Hayes is challenged by Dillon Scott in the 12th District. As of Friday, only five candidates have begun qualifying for the six seats on the Charlotte Town Council to be filled Aug. 7. Incumbents Donnie Allen, Gene Miller and Tim Reynolds are seeking re-election while Tommy Brewer and Alex Spann have picked up qualifying petitions. Incumbents Jim Robertson, Sheila Sesler and Sherrie Thiel have yet to begin the qualifying process. In the local legislative races, Republican incumbent Mary Littleton remains the only candidate in either primary for the 78th District seat in the House of Representatives. 69th House District incumbent David Shepard is unchallenged in the Democratic primary but faces general election opposition from Michael Curcio, the only Republican candidate so far. First-term incumbent Republican state Senator Jim Summerville of Dickson faces three challengers in the GOP primary for the 25th District: Rep. Joshua Evans of Greenbrier, former Sen. Kerry Roberts of Springfield and Wayne White of Slayden; while Tony Gross of Kingston Springs is the only Democratic candidate at this time. Qualifying for the Aug. 7 county general, state primary and Charlotte municipal elections ends at noon April 3.
