Throughout her campaign, Senator Elizabeth Warren has largely sidestepped the question of sexism. It’s a lose-lose situation: Women candidates don’t want to seem whiny, but they also don’t want to look weak if they’re insulted or discriminated against because of their gender.

When CNN reported on Monday that Bernie Sanders told her in 2018 that a woman could not be elected president, Warren seemed trapped. She could call out Sanders for sexism and risk seeming shrill or petty. Or she could let the story pass without making anything of it. On the debate stage in Iowa Tuesday night, Warren chose a third path: She argued that being a woman is not a liability for political candidates. It’s a strength.

To make her case, Warren pointed to hard evidence, invoking the records of her competitors in the Democratic primary race. “Look at the men on this stage,” Warren said. “Collectively, they have lost 10 elections. The only people on this stage who have won every single election that they’ve been in are the women: Amy [Klobuchar] and me.” And she’s more than prepared to take on President Donald Trump as a woman, she added: “The only person on this stage who has beaten an incumbent Republican anytime in the past 30 years is me.”

Perhaps the strongest piece of evidence for her argument is the 2018 midterm elections, when women won a record number of seats in Congress, beat out male opponents in key swing states including Florida and Pennsylvania, and earned greater representation in the U.S. Senate and governors’ mansions across the country. The Democratic Party’s recent successes, she said, are owed to women candidates and women voters.

Warren’s answer was met with loud cheers from the debate audience at Drake University. But her strategy is more significant than any one applause line.

In the three years since Hillary Clinton lost the 2016 election to Trump, pundits and political watchers have spent endless hours parsing the role of sexism in that election. Clinton was widely hated on the right for a number of political and historical reasons, but many of her supporters believed at least part of that hatred stemmed from misogyny and a deeply held belief among American voters than a woman can’t be president.

Sanders denies ever telling Warren that a woman could not get elected. He pointed to a decades-old video of him encouraging little girls to run for office, and to the fact that he hung back on entering the 2016 Democratic race in hopes that Warren would run. “How could anybody in a million years not believe that a woman could become president of the United States?” he said during Tuesday’s debate. “Let me be very clear: If any of the women on this stage—or any of the men on this stage—win the nomination … I will do everything in my power to make sure that they are elected in order to defeat the most dangerous president in the history of our country.”

But Warren managed to move the conversation to a new level—past any disagreement with Sanders, past a referendum on what happened to Clinton in 2016, past a debate over how sexist America really is. Women candidates and voters will once again be crucial players up and down ballots in 2020, Warren argued, and they’ve proved that they can win against men and Republicans alike. And besides, she said, this is not the first time people have questioned whether a candidate’s identity will hinder electoral success. “Back in the 1960s, people asked, ‘Could a Catholic win?’” she said. “Back in 2008, people asked if an African American could win. In both times, the Democratic Party stepped up and said yes, got behind their candidate, and we changed America. That is who we are.”
