This is such a bad, and bullshit, take. Half of male candidates lose too. The odds of 2/2 female candidates losing is pretty damn high, and one of those candidates didn't even have 99% of the campaign, and she still wasn't that far off.
Those two candidates were just shit candidates. They were even more shit than the average Democrat candidate. They didn't lose because they were women. They lost because they campaigned on status-quo, neoliberalism, pro-corporate ideas that inspired no one. AOC isn't that. The only thing they have in common is being women, and it's a complete fabrication to say there's any solid evidence those other candidates lost because they're women.
