Marty Haynes was successful in unseating County Commissioner Mitch McClure in the District 3 Republican Primary.
Haynes, a 52-year-old lifelong resident of Hixson, will now face Democrat Mitzi Yates in the general election. Haynes unsuccessfully ran for the District 3 school board seat in 2010.
McClure, pastor at Middle Valley Church of God, was appointed interim commissioner following Jim Coppinger’s appointment to Hamilton County mayor last year. Tuesday was his first election in District 3.
