Milwaukee election officials are reporting ballot shortages at voting sites due to what they say is “unprecedented high turnout” in Tuesday’s spring election.

Seven polling sites were totally out of ballots and election officials were working to replenish the supply. They are also checking with other sites that are low on ballots.

Anyone in line by 8 p.m. will be able to vote, Milwaukee Election Commission Executive Director Paulina Gutiérrez said Tuesday evening.

Officials said no voters would be turned away due to the shortages, and voters can call 414-286-VOTE with any concerns or questions.

Election officials have increased field staff and sent ExpressVote machines that are used at early voting to those locations, along with additional ballots, she said. The ExpressVote machines allow voters to make their selections on a screen and print a ballot that can then be fed into the machine that tallies the votes.

“The fact that this is historic turnout in the spring election, which has never occurred here in the city, feels great,” she said. “We apologize for the delays that are happening. We ask you to remain patient. Please stay in line.”

Any voters who are told they cannot vote should alert election officials immediately, she said, adding that “absolutely should not happen.”

Gutiérrez said the Election Commission put in two additional orders of ballots about a week ago after seeing how busy early voting was.

But the turnout on Tuesday meant the sites went through those additional ballots, forcing the Election Commission to print additional ballots. The printing can be a slow process, she said.

On the ballot is the

nationally watched state Supreme Court race

in addition to the race for state superintendent.
