"In a nation of 333 million Americans, almost 160 million (66%) of its 239.2 million eligible voters cast votes. That’s the highest voter turnout rate (if one considers bulk-mail balloting “turnout”) among eligible citizens since 1900, when 73% of voters actually turned out in person to cast ballots in the race between Republican President William McKinley and Democrat challenger William Jennings Bryan. Elections were close then, too, with McKinley winning with a little more than Biden’s margin — 51.6% of that vote."
