The announcement arrived after a disappointing Super Tuesday for the progressive candidate, who failed to win her home state of Massachusetts. “I refuse to let disappointment blind me— or you—to what we’ve accomplished,” Warren wrote. “We didn’t reach our goal, but what we have done together—what you have done—has made a lasting difference. It’s not the scale of the difference we wanted to make, but it matters—and the changes will have ripples for years to come.”

Warren built a successful grassroots movement and, for much of the race, was a Democratic front-runner. She supports key issues like the Green New Deal and Medicare for All, and she mapped out proposals for affordable housing and free college for lower-income students. Her liberal policies earned her numerous comparisons to Bernie Sanders, but as Warren fell behind and her more moderate opponents, like Amy Klobuchar, Michael Bloomberg, and Pete Buttigieg, exited the race—each endorsing former Vice President Joe Biden—it became clearer that her participation might be splitting the progressive vote. Her choice to bow out for the sake of the country’s future is honorable, but her departure makes the Democratic nomination a toss-up between Sanders and Biden as congresswoman Tulsi Gabbard trails behind significantly. That shouldn’t be the case.

Yes, Biden has decades of experience; he first became a senator in 1972, while Warren wouldn’t be elected until thirty years later. Despite serving two terms as vice president, however, Biden failed to match Warren’s sharp wit in debates—his muddled answers and seemingly inattentive performances spurred headlines like “Is Joe Biden OK?” Additionally, there’s an ongoing list of allegations about his creepy behavior towards girls and women, for which he’s never formally apologized.

When it comes to policy, Biden can be moderate to a dangerous degree. His stance on abortion has wavered throughout the years (to be fair, Warren was a Republican until the ’90s), and he supported a constitutional amendment in the ’80s that would have let states overturn Roe v. Wade. In the ’90s, he voted against legalization of gay marriage, and later in the early ’00s, he voted in favor of the Iraq War. Today, he opposes Medicare for All, would let states individually allow to legalize recreational marijuana, doesn’t believe in abolishing ICE, and wouldn’t bring U.S. troops home from overseas; Warren’s stance on each of those issues is the opposite, which makes the trending #WarrenToBiden hashtag so disappointing.

Though Warren has generally kept her gender out of her campaign (aside from telling little girls that she’s running for president because “that’s what girls do”), much of Biden’s sudden lead ahead of her can be accredited to sexism. Despite experience, Warren has proven time again and again that she’s incredibly fit to be president; how has Biden become our most “electable” option?

Yes, Democrats need to unite to ultimately defeat Donald Trump. But we also can’t risk electing a candidate who repeatedly appears mentally unwell, poses dangers to women, and doesn’t have an aggressive plan to tackle the climate crisis. Thankfully, we have a viable candidate left with Sanders, but Biden shouldn’t be the other choice. The U.S. deserves better than Biden, but it’ll be hard to get there until we’ve overcome our fear of electing a woman.
