But others disagree, citing Obama's relative inexperience with respect to McCain's.
"I'm looking for experience," said Brian Armour, another GM worker, expressing his preference for McCain. "I really don't think what we have available to us in one candidate has the experience the other one does."
"I'm putting country first and voting for Obama," said Harris, borrowing from a McCain slogan.
Harris said that he thinks that Obama is "putting country first" by looking out for the middle class.
And Mike Hughes, who has worked at the plant for 10 years, is still undecided.
"The biggest thing is taxes. That's what will swing my vote," Hughes said. "Who's going to give us the best deal out there to try to turn this economy around?"
Next door to the GM plant, at the Upper Deck Tavern, owner Debbie Miller has seen her revenue drop considerably.
"I'm looking for the next president who's going to help me stay in business," Miller said.
Ohio remains an important swing state: Obama has visited 23 times since clinching his party's nomination; McCain 30 times. The two candidates have broadcast a total of 50,000 television ads in this state. Despite all those visits and all those ads, two local real estate brokers having lunch at the Upper Deck Tavern said the state is still to be won..
"I think that there are still very many undecided voters, and I think if one of them can come up with a few solutions for the economy right now, they will be the winner," Kathy Foland said.
Ohio has voted for the winner of the last 11 presidential elections, making this state a true bellweather state.
"All kind of politicians from both parties have come to Dayton and have always said that they would deal with economic issues, like unemployment, in Ohio and in Dayton," said Heitmann. "And it seems like very little has been done. So, they're here to get votes, but then we don't see them again."
For voters like these who have GM in their blood, to win their votes and maybe the nation, the candidates must first address the economic concerns plaguing Ohio.
