On Tuesday, Nate Silver of FiveThirtyEight tweeted out a graphic showing the current split between male and female voters in the election.
According to Silver, if only women voted, Hillary Clinton would win by a landslide. However, if only men voted, Donald Trump would dominate.
Trump's son Eric later sent out the male map in a fundraising email in a bid to inspire supporters, but neglected to mention the map only showed men voting. He was subsequently mocked online.
