Historically, in presidential years, women make up a larger share of the electorate than men. In 2012, for example, 53 percent of voters were women and 47 percent were men, according to NBC News Exit Poll results.

Trump’s campaign has needed to appeal to women voters in a big way and the past week—from his debate performance to his feud with former Miss Universe Alicia Machado and his reported sexist behavior during his reality TV years—has shown that he still has more work to do to secure women voters.

Among women likely voters, a majority—52 percent—said they support Clinton compared to 34 percent who said they support Trump; 8 percent of women voters said they support Johnson and 3 percent said they support Stein.
