In recent decades, the “gender gap” has become one of the defining and enduring characteristics of American elections, with women more likely to support Democrats and men more likely to support Republicans. In the 2012 election, for example, President Obama earned 55% support from women voters, while Mitt Romney received 52% of men voters.Over the last quarter-century , men have only supported the Democratic candidate twice, while women haven’t supported the Republican candidate at all.This year, of course, it’s likely the gap will reach new and unprecedented extremes, with Donald Trump alienating women so dramatically, at times it seems he’s trying to lose. With that in mind, FiveThirtyEight’s Nate Silver published an interesting item yesterday, noting what the electoral map would look like if only women voted. In short, it’d a landslide: Hillary Clinton would win with 458 electoral votes. Naturally, the inverse is also true: Nate also posted a comparable electoral map showing that Trump would win with 350 electoral votes if only men voted.As BuzzFeed noted , the twist came this morning when Eric Trump sent an email to his father’s supporters, asking for money, and featuring the male-only map as proof of Donald Trump’s “momentum.”
