MILWAUKEE, (CBS 58) -- We are now just days away from the midterm elections, which means preparations are underway.

"At the end of the day, we make sure that every eligible ballot is processed through the machine," said Paulina Gutiérrez, the Executive Director of the Milwaukee Election Commission.

Ballot tabulators lined the walls of the Milwaukee Election Commission's Central Operations Center as they make their final checks before election day on November 3rd.

"We obviously care about free and fair elections, ensuring the safety and security of every single eligible vote," said Gutiérrez. "We have to do this multiple times and then we do it in public so you can see what was replicated in LNA. "If a machine doesn’t pass, it will not be used on election day."

On Saturday, the MEC provided demonstrations of the high-speed tabulators that will be used at central count, and the machines used at polling locations across the city, giving a behind the scenes look at the process.

It's something election attorneys Bob Bauer and Ben Ginsberg say make all the difference to remove doubt from voters in the election process.

"There’s a very common thread about how the system works, what safeguards are built into it and in that since we don’t hear anything here that’s strikingly different than what we hear elsewhere, but as you know all cross the country," said Bauer. "There’s an elevated interest in this topic for obvious reasons."

In August, a wrong button pushed on tabulators caused delays in the absentee ballot downloading process and high voter turnout last year in April caused several locations to run out of ballots.

Gutiérrez says those came down to human error, not an issue with the system.

"We will always have human error because we’re human beings, but the election process has multiple layers of security, multiple layers of checks and balances," said Gutiérrez. "We have paper copies, paper ballots, voter numbers, poll books, machine reports and we are constantly checking to make sure that a ballot matches an eligible voter."

The Wisconsin Elections Commission says they expect more than 2.6 million Wisconsinites to cast their ballots for this election.
