NBC published this editorial from David Brock, a self-identified former Right Wing Hitman, who switched sides, started working for centrist Dems, and spent 2016 smearing Bernie so dirtily that his colleagues in the Clinton camp publicly begged him to stop.

“I think [Bernie Sanders is running the most negative campaign of any Democrat in primary history]. All of these attacks on Secretary Clinton at the end of the day are character attacks. They’re very personal they’re totally unwarranted.” — David Brock “Black lives don’t matter to Bernie Sanders.” — David Brock “I was prepared to bring [Bernie Sanders’ medical records] up.” — David Brock “.@davidbrockdc: chill out. We’re fighting on who would make a better President, not on who has a better Physical Fitness Test.” — Hillary Clinton advisor John Podesta “For God’s sake stop David. This is very harmful to HRC. No one I know who supports HRC is anything other than repulsed and disgusted by your call for medical records release. I am talking about dozens of people all day today. Please please stop this and apologize.” — Hillary Clinton surrogate Lanny Davis “I hope Hillary truly understands now how batshit crazy David Brock is…. Trusting David Brock probably doesn’t make a lot of sense. I mean I hope people get he’s kind of a nut bar…. David Brock is like a menace. I continue to believe he’s the manchurian candidate of the GOP — secretly out to tank her….. I honestly think david Brock is a conservative plant.” — Clinton ally Neera Tanden “ I was criticized for being too aggressive in my support for Secretary Clinton — and rightly so. Looking back, I recognize that there were a few moments when my drive to put Hillary in the White House led me to take too stiff a jab. I own up to that, I regret it, and I apologize to you and your supporters for it.” — David Brock “Really? Is that [smear] what they’re saying? Based on what…? Based on David Brock’s long history of honesty and integrity? The man who tried to destroy Anita Hill?” — Bernie Sanders [Anita Hill is] “a little bit slutty, a little bit nutty.” — David Brock “Hillary has failed because she never really accepted the simple truth that legal and ethical structures and standards of accountability exist not just to protect us from the ambitions of the wicked but from the hubris of the good.” — David Brock
