This one was easy, campaigned and followed daily for Sanders in 2016. The constant charade and collusion inside the DNC against Sanders at the time was apparent and became factual with court cases and leaked documents. It's why Debbie Wasserman Schultz lost her position as chairwoman (should've been banned from the party, but that would be holding people accountable).

Wasserman Schultz was elected chair of the Democratic National Committee in May 2011, replacing Tim Kaine.[2][3] On July 28, 2016, she resigned from that position after WikiLeaks released leaked emails showing that she and other members of the DNC staff had favored Hillary Clinton over Bernie Sanders in the 2016 Democratic primaries in exchange for funding to eliminate the DNC's remaining debt from the 2012 presidential campaign.[3][4] source

I would categorize @Eldritch@lemmy.world as a disinformation troll at this point. It's one thing to be wrong, but to lie with insults and not step back any statements is a sign of someone who doesn't care because they already did what they sought out to do.

Definitely always do the research if you have time to respond, there's plenty of times I've been misinformed till I start digging into it and always try to apologize with a correction to my statements.
