Bernie Sanders is indeed an Independent, and Elizabeth Warren is a registered Democrat who has consistently rejected the democratic socialist label throughout her career, instead identifying as a progressive capitalist. The post is factually accurate — Warren explicitly distinguishes herself from democratic socialists like Sanders. The reference PolitiFact fact-check addresses a separate false claim about Sanders and the Socialist Workers Party from 2020, which is unrelated to this post's narrower focus on party affiliation and self-identification.
