Nate Silver from FiveThirtyEight looked at the polls and calculated that Clinton was on average 10 points above Trump among women in every state.
FiveThirtyEight then added 10 points to Hillary Clinton's polls-only margin in every state to see what would happen if only women voted.
This would put her ahead in Alaska, Arizona, Georgia, Kansas, Indiana, Missouri, Montana, South Carolina, South Dakota, Texas and the 2nd congressional districts in Maine and Nebraska.
Trump is 10 points above Clinton among men across the polls, so FiveThirtyEight did the same to the map for him and found that if only men voted, "Trump would win everything that could plausibly be called a swing state, with Clinton hanging on only to the West Coast, parts of the North-East, Illinois and New Mexico."
In conclusion, they predicted if Trump loses, it's because women voted against him.
The data went viral on social media, and split opinion.
RealClearPolitics.com has Clinton leading Trump in national poll averages by 6.2 per cent - a landslide figure should it hold until election day on November 8.
