CLEVELAND (NewsNation Now) — What happens to ballots mailed in and dropped off before the big election next month?

NewsNation affiliate WJW-TV went inside a Cuyahoga County Board of Elections warehouse to get a glimpse of what voters never see.

All ballots mailed or dropped off go through a very large room buzzing with machines and dozens of people.

In one area, ballot envelopes get opened. Across the room, ballots get sorted. And, in another section, employees check ID’s and birth dates and confirm ballots turned in are legit and should be counted.

The Board of Elections understands you may see all of that and want to know how nothing gets lost. Workers say voters should trust the system.

“We’ve honed it down to a very effective system,” said board spokesman Mike West said. “We have checks and balances every step of the way. The machines are a big help and a tool to make things go fast. But, there’s some things we need human beings to do.”

One voter dropping off a ballot told us, “I completely care what happens to my ballot. I just asked the gentleman was he sure my ballot would be counted?”
