People of Color and AA especially have been supporters of the Clinton's for decades. She's been there, in the community, since the beginning. Her work with the Children's Defense Fund was the basis of her political ideology. She has deep roots within the community that only President Obama was able to break.
Bernie has zero connections to the AA community because he's never, ever had to even try to appeal to it before. He comes from lily-white Vermont. He has probably never had to worry about tailoring his message to different demographics...and he still can't do it now.
Also, AA;s, especially southern AAs, are more conservative than white liberals. They also tend to be more pragmatic in how we should deal with issues. You add to that Bernie's rather weak stance on guns, his lack of engagement with the community, his poor handling of BLM, his refusal to understand basic intersectionality and you have a candidate who is out of touch with the views of many non-whites.
The amount of outright lies about Bernie's record in this post tho.
Minorities don't like Bernie likely because of two reasons. The first is that they are hardly familiar with him and are familiar with Clinton.Hillary Clinton has been a household name since the early 1990s. The Clinton's became very popular with minorities. But Sanders? Who the fuck is Sanders? Just some random guy from Vermont who appeared at the stage. The second is that Sanders is from Vermont which is racially homogeneous, compared to Hillary who is experienced in New York which is very diverse. Hillary knows how to campaign to minorities, Sanders has zero experience with that. It takes years of experience to know how to reach a demographic. Peope could point to Obama, but he was a community organizer...
He's a dude who has been there for a long time battling for and with all kinds of minorities. But don't let facts cloud your false talking point about Bernie.
