Women make up more than half the population of the United States and are powerful voting bloc that both presidential candidates are trying to reach. But what if the 157 million women in the United States were the only voters in a presidential election?

On Tuesday, Nate Silver of FiveThirtyEight tweeted a map showing how the electoral map would look if only women voted.

Followed by a second tweet about if only men voted.

And then some Trump supporters on Twitter started calling for the repeal of 19th Amendment, which gave women the right to vote in 1920.

I would be willing to give up my right to vote to make this happen #repealthe19th https://t.co/vndQu9dKFP — OUR PRESIDENT TRUMP 👍⭐️🇺🇸⭐️🇺🇸 (@PrayHealourland) October 12, 2016

The gender dynamics of the race between Hillary Clinton and Donald Trump are unprecedented.

They have become an even bigger part of the campaign since tapes from 2005 surfaced last week in which Trump brags about pursuing a married woman and says he doesn't "even wait" before kissing women he finds beautiful. "When you're a star, they let you do it," he says.

On Wednesday, two women told The New York Times that they had been sexually assaulted by Trump.

Also on Wednesday, Eric Trump sent a fundraising email using the all-male-voter map titled "Momentum" Buzzfeed reports.

Clinton and her campaign have owned her feminism more openly this campaign cycle. At multiple campaign events, including the Democratic National Convention, Clinton and her surrogates have discussed the start of the women's rights movement at the Seneca Falls Convention in 1848.

The narrative around women's suffrage for many is seen as a war that women won. In fact, the first people to ever picket the White House were suffragettes in 1917. The video below details more about the history of the movement.

It is with that in mind, that many women responded to the Twitter hashtag and called out other women who were not supportive of the amendment.

For anyone who thinks sexism doesn't exist and fighting for women's equality doesn't matter anymore: #repealthe19th is an actual hashtag pic.twitter.com/1eEl2q6vt9 — Meredith Stark Metaxas (@mgstark) October 12, 2016

My suffragette sisters didn't fight tooth and nail to get the vote for Trumpers to waltz in and be even more deplorable. #repealthe19th pic.twitter.com/7lNYujXJRQ — Anna Louise 💁🏼✨ (@owlyannie) October 13, 2016

Don’t understand women who are on #RepealThe19th. You’d give up your right to vote to be nothing but lesser than men? Pathetic. — Christine Romero-Chan (@christyxcore) October 13, 2016

Why is #RepealThe19th a thing? Apparently weak men can't handle empowered women. pic.twitter.com/Bzc2sFjqwq — Arisha Ali (@ali_arisha) October 12, 2016

And then, internet being the internet, there were some tongue-in-cheek tweets as well:
