The Wisconsin Elections Commission is predicting that 3.1 million people will cast ballots for the election.
According to census estimates, that's 69.6 percent of Wisconsin's voting-age population.
"We typically look at history for guidance in predicting turnout. We expect turnout for this election to be similar to previous presidential elections," said Michael Hass, Wisconsin's chief elections official.
Even though absentee voting has been growing in popularity, it is not necessarily an indicator of a higher overall turnout, Haas explained.
As of Thursday morning, 623,503 absentee ballots had been returned to municipal clerks for counting on Election Day.
Over the last 50 years, the highest voter turnout percentage in a November presidential election was 72.9 percent in 2004. Despite this, the highest number of voters to participate in a presidential election was 3,080,628 in 2012.
