Marion County mayor appointee John Graham held off challenger Mack Reeves for the Democratic slot on the August general election ballot with a win in Super Tuesday's local primary contest.

"I'm just gratified that I was able to win another countywide election," Graham said. "I'm glad to have jumped this hurdle, and I'm ready to go on to the next election in August."

Administrator of Elections Gary Reames said voter turnout through the day was slow.

Democratic primary winner Graham will face Republican candidate Gary Ellis in the battle to serve out the remaining two-year term, records show.

Graham was appointed in December 2010 to replace the late County Mayor David Kirk, who died in November 2010, until the seat could be decided on the August general election ballot.

Kirk died of complications from a horseback riding accident. County Commission Chairman Gene Hargis became interim mayor until commissioners met to vote on an official replacement.

Graham was serving his 15th year as road superintendent when he was appointed.

All vote totals, which include federally mandated provisional ballots, are unofficial until certified by the Tennessee Division of Elections.
