Dayton could have runoff votes for both mayor and city commission May 7, as five people filed petitions to run for mayor before the 4 p.m. Friday deadline, and six filed for the commission race.

Only three of those 11 have been approved for the ballot so far by the Montgomery County Board of Elections, but the board will meet Wednesday to determine whether the other eight have the 500 or more valid signatures from Dayton voters needed to make the ballot.

Those filing to run for mayor were current Mayor Gary Leitzell, retired physiologist Eric LaMont Gregory, former judge and county auditor A.J. Wagner, city commissioner Nan Whaley and Derek Folley. Only Whaley is certified by the BOE so far.

The six who filed to run for city commission were incumbent Joey Williams, advertising agency owner David Esrati, state school board member Jeffrey Mims, Northwest Priority Board Chairman David K. Greer, past city and county candidate William Pace and digital media company president Joseph Lutz. Only Esrati and Williams have already qualified for the ballot.

If three or more candidates are certified to the ballot for mayor, there will be a runoff May 7, with the top two vote-getters advancing to the November election.

In the commission race, at least five candidates must be certified to the ballot to trigger the May 7 runoff, with the top four vote-getters advancing (because there are two seats up for grabs).

Steve Harsman, deputy director of the BOE, said the last time Dayton had a runoff vote in a commission race was 2003. The last runoff for Dayton mayor was in 2005.

More than 25 people initially took out petitions to run for commission or mayor, indicating an interest in running. Harsman said it is common for many people who take out petitions not to follow through.

Among those who took out petitions but did not file was Darshawn Romine, who took part in a mayoral candidates’ forum last week. Mark Manovich, who ran for commission in 2011, and Tim O’Bryant, who ran for county recorder last fall, took out petitions to run for commission, but did not file.
