Now that Sen. Elizabeth Warren (D-Mass.) has dropped out of the race, the questions and allegations about how sexism may have hindered her candidacy are making the rounds.

Warren pointed to her gender as an obstacle in earning the nomination, now that the remaining contenders are white men in their late-70s.

"[Sexism] is the trap question for every woman," Warren said Thursday. "If you say, yeah, there was sexism in this race, everyone says, 'Whiner.' And if you say no sexism, about a bazillion women think, 'What planet do you live on?'"

Sen. Kamala Harris (D-Calif.), as her own campaign was declining, also wondered openly about whether America was ready for a female president. And now that Warren is out, Harris has revisited the question.

"This election cycle in particular has also presented very legitimate questions about the challenges of women running for president of the United States," Harris said Thursday, CNN reported. "Look at what's happened. There are no women currently in this race...but the reality is that there's still a lot of work to be done to make it very clear that women are exceptionally qualified and capable of being the commander in chief of the United States of America."

There is, however, evidence that sexism was not Warren's problem, but rather a general and widespread unpopularity across demographics — including women.

Warren not only lost her home state of Massachusetts, which is embarrassing enough for an allegedly serious presidential contender, but in her home state she also lost the female vote to former Vice President Joe Biden.

According to Massachusetts exit polls, Biden beat her by 10 points with women. Sanders beat her by 7 points with "very liberal" voters and by 14 points with voters who support Medicare for All. And the former college professor lost college educated voters by 5 points to Biden.

There are certainly some voters who believe a woman is less qualified than a man to be president. But even if you take that away, Warren probably had too many issues to overcome to have a chance at the nomination. She lied about her race. She was dishonest about the tax implications of her policies. She tried to make personal wealth the worst thing in the world in a country where people aspire to be personally wealthy. Even Sanders, despite still having a chance at the nomination, is learning that some of those issues can cause problems with voters.
