The opening of the polls in Illinois Tuesday morning didn't come without frustration for some.
In Chicago's Hyde Park, voters could be seen standing in line for several minutes after the polls were set to open at Kozminski Community Academy.
Officials said the building's engineer arrived nearly an hour late, but noted that those in line at 6 a.m. were able to vote by 6:30 a.m.
"We apologize profusely," said Marisel Hernandez, chairwoman for the Chicago Board of Elections. "All voters were able to vote and that’s what we’re glad about."
As polls officially opened across Illinois, elections officials were preparing for a large number of voters to cast their ballots Tuesday.
“We’re expecting a much better turnout than four years ago,” Hernandez said.
In Cook County, election officials have estimated a record 1.5 million residents are registered to vote.
As of Tuesday morning, 108,000 early ballots had been cast in Chicago. That number exceeds the 45,013 early voters from the 2010 primary and the 36,113 total from 2014.
In suburban Cook County, nearly 92,000 early votes were recorded by Sunday night.
The record for the number of early votes in a gubernatorial primary election in suburban Cook County, set in 2010, was shattered last Monday with one week of early voting still remaining.
Vote by mail applications in Chicago were also nearly five times the number reported in 2014 and almost triple the totals in 2010.
“Given those early voting numbers I think we’re going to see the highest voter turnout on today, Election Day,” Hernandez said.
