If anything, Warren explicitly benefited throughout the campaign from being female, using her gender to play the victim card, even when doing so required fudging the facts or entirely reinventing them to suit her purposes, as in the case of her disproven allegation of pregnancy discrimination.
Perhaps the best example was when Warren spun several news cycles out of her assertion that Bernie Sanders is a sexist, alleging that he had once told her a woman could never be president. He strongly denied this several times. Moderators raised the matter in a debate, only to deny him time to respond. They treated Warren’s unproven assertion as a fact and instead repeatedly silenced Sanders on the topic, while Warren continued to attack him unchallenged.
The notion that Elizabeth Warren’s presidential hopes were dashed by an American electorate not ready for a female president is pure wishcasting, indulged in only by media elites who believed that her campaign was destined to succeed largely because they had thrown their weight behind it. For anyone watching the race with clear eyes, it is evident that Warren’s biggest flaws were not her chromosomes but her inept political maneuvering and her pattern of dishonesty.
