It's National Manufacturing Day, a day established to focus on the importance and challenge of making things in America.

Measured by its almost 17 percent of Ohio's economic output, manufacturing is the biggest sector of Ohio's economy.

There are 14,200 companies employing 663,000 workers in Ohio's manufacturing sector. And owners and workers are listening to what both candidates are saying about their plans to create new jobs and restore lost jobs.

"I have a very good idea how a President can help create jobs because, over the eight years when my husband was President, we created 23 million new jobs," Hillary Clinton says, on the campaign trail.

She pledges to create a $10 billion Make It in America Fund that would partner companies, unions, local governments and universities to promote manufacturing.

She would fight trade abuses, give businesses incentives to invest in communities hard hit by job loss, punish companies moving jobs overseas and reward companies bring them back to the U.S.

A recent study claims Ohio lost more than 112,000 manufacturing jobs in 2015 because of trade deficits with Transpacific Partnership countries.

"Our county is losing companies. Our country is losing jobs. Our trade deficits are massive all over the world " is Donald Trump's message on the campaign trail.

His manufacturing plan focuses on trade.

He's having the United States withdraw from the TPP, fight trade deal violations, try to have world organizations punish China's currency abuses and renegotiate NAFTA.

His manufacturing of his shirts, ties and other products overseas is fodder for Clinton on this issue.

Some observers say both candidates offer unrealistic hope of bringing back manufacturing jobs because the world has changed. Manufacturing is now more about fewer people using technology to make more things.

Both candidates spend much time on the manufacturing jobs issue when campaigning in states like Ohio, Michigan and Pennsylvania.
