Early voting turnout is set to rival the 2018 midterms, with more than 11 million ballots already cast in the upcoming midterm election, according to data from the United States Election Project, run by University of Florida political science professor Michael McDonald.

Thirteen days out from Election Day, voters in some states are coming out in numbers similar to 2018, when some of the highest turnout in U.S. history was recorded, ABC News reported.

“It does seem very robust, early voting,” McDonald told ABC News. “I think we’re looking at more like a 2018 election, definitely.”

Voters in 40 states are able to cast ballots either in-person or by mail as of today, according to the United States Elections Project.
