Republican incumbent Joe Hintz will square off against Democrat Melissa James and independent Bob Morgan.
Morgan just filed his petition to run, while Hintz and James ran unapposed in the May primary.
Hintz, who is completing his second four-year term, received 3,087 votes. James, who recently stepped down as director of the Huron County Chamber of Commerce, received 1,474 votes.
The winner will join Terry Boose and Skip Wilde, who both have two years remaining on their terms.
Just 6,910 of the 36,050 registered voters (19.17 percent) in Huron County cast a ballot in the May 8 election.
This will be the third time Morgan is running for commissioner. He ran four years ago against Hintz and then two years ago against Wilde. Both were in the primary election.
Why is Morgan running again?
“So people have a choice,” he said. “I want to be on the November ballot. Do you know how many people vote in the primary election? It’s terrible.
“I talked to a lot of people who said they were going to vote for me in November. It doesn’t work that way. They just don’t know.”
Morgan, who retired from the Ohio Department of Transportation and is the longtime president of the Huron County Fair Board, said he lost to Hintz by 38 votes the first time he ran and “400-some” when he ran against Wilde.
