As Ohio voters cast ballots in Tuesday's presidential primary, the economy — specifically manufacturing jobs — will be front and center on many voters' minds.

"We have to have a strong manufacturing base for this country to survive," said Brandon Lamoncha, sales manager and solution provider at Humtown, a third-generation, family owned manufacturer in Columbiana, Ohio. "I have to vote later today and I'm still undecided. I really don't know," said Lamoncha, who is a registered Republican and has supported Gov. John Kasich in past local races.
