“Black trans and cis women, gender-nonconforming, and nonbinary people are the backbone of our democracy.”

This embarrassing, obsequious, pandering line, tweeted by Elizabeth Warren in November as her campaign began its fade into oblivion, tells half the story of why she failed.

The other half is a lot simpler: She’s a liar.

Warren’s pandering during this campaign was legendary, and, like all pandering, it evinced the candidate’s deep insincerity.

Warren famously promised to have a preteen child with gender dysphoria vet her appointment for secretary of education. She claimed that Michael Brown, a grown man shot in the act of aggressively assaulting a police officer in his own squad car, had been “murdered.”

In a way, it’s sad that Warren will never get to fulfill her promise of appointing a cabinet that is 50% “filled by women and nonbinary people.” It would have been interesting to watch angry arguments over whether biological males identifying as women should be able to take these set-aside spots at the expense of qualified female applicants.

That a candidate who panders so much should also habitually tell calculated, self-promoting lies is not a huge stretch. In Warren’s case, it was merely an extension of her insincerity by other means.

Yes, Warren tells the typical political whoppers — for example, advancing proposals she cannot pay for and obfuscating when called on it. But that’s not unique to her. In fact, Warren’s dishonesty goes beyond any of the remaining Democrats in the field and arguably makes her one of her party’s most prolific liars.

Warren famously spent years masquerading as a Native American. This only ended last year, when she bizarrely revealed a DNA test that showed she was probably not Native American at all. Warren also insisted up and down for a long time that she had never used her American Indian identity to advance her professional career. That turned out to be a lie, which helped explain why Harvard Law School once touted this whitest-of-all-white person as a Native American hire.

Warren has since lied about her father being a janitor as part of her story of humble origins. Her brother angrily explained to reporters that, no, this was not true and that Warren was just exaggerating her family’s poverty at the expense of her father’s memory.

Warren also lied about having sent her children to private school. She did not merely conceal that she had but actually lied, saying, “No,” she had not, when confronted by school choice parent activists. In fact, Warren’s son attended a private school, though her daughter also attended public school. This was inconvenient for her because Warren is an ardent opponent of all school choice programs and the school reform movement, which President Barack Obama at least partly supported. She lied in order to conceal her hypocrisy in sending her child to private school while denying others, mostly nonwhite parents, the opportunity to choose quality schools for their children.

Speaking of education, Warren tells a story and, in fact, repeated it in a recent debate about being pushed out of a teaching job because she was “visibly pregnant.” This highly suspicious account is contradicted by both contemporaneous documents and an interview Warren herself once gave about that time in her life. The record shows that Warren was offered an extension in the position in question but turned it down, and, in her 2007 interview, Warren said she had quit the teaching job because she didn’t think her ongoing graduate studies in education were “going to work out for me.” Warren said absolutely nothing at that time about being fired for being pregnant, but she started running for president, and, suddenly, her story conveniently changed.

In this presidential race, Warren tainted herself to the point that no one should be interested in her as a vice presidential nominee. It will be tempting, though, because Warren did prove to be good at one thing all veep candidates are supposed to do. She is an assassin. She utterly and deservedly destroyed Michael Bloomberg’s campaign on the debate stage. What the news mogul had spent half a billion dollars building up in a self-funded campaign, Warren ripped to shreds in a matter of minutes.

It was glorious to watch, in Bloomberg’s case. It’s a good thing, though, that Warren won’t have the opportunity, as president, to destroy value in a similar manner in the broader economy.
