"Bernie's supporters have been very, very damaging to him, and it's really frustrating to see and experience. They don't realize how influential they are. It's frustrating to feel like they are hurting him," Ocasio-Cortez said in the midst of the 2020 primary, according to the book. "I feel like Warren is scooping up LGBT, progressives, women, and progressives of color because of how they isolate."
She also worried that the behavior of Sanders's supporters were "forcing an unnecessary choice between class analysis and race analysis" through their "behavior, not so much policy."
Ocasio-Cortez made those comments as she mulled whether to endorse Sanders's 2020 campaign, even though she had worked as an organizer on his 2016 campaign.
Yes, because the "BernieBro" thing was mostly an online thing. In other words, that was just very online Hillary/Biden/Warren people crying because young people cared more about another candidate. But it was made into this huge issue by the mainstream media, I am betting that it received more TV time in 2016 and 2020 than the Iraq war and climate change combined.
