Americans were prepared for the 2020 U.S. Presidential Election to be historic for a number of reasons, and so far data is backing that up at least in one aspect: voter turnout. More Americans voted in 2020—and voted by mail—than in any other election in U.S. history. While the final turnout number will be available when all ballots are counted in the coming weeks, already two-thirds of Americans eligible to vote participated—nearly 160 million people, up from around 138 million in the 2016 election—a proportion not seen in more than a century, according to preliminary estimates posted Wednesday by Michael McDonald, professor of Political Science at the University of Florida who runs the United States Elections Project, a website that tracks voter-turnout data.
