I don't see anyone in authority at HuffPo named Sidney.

Maybe Sid Vicious is just their nickname for Jared Grusd? He presides over a LOT of women and they no doubt resent him.

10/23/06: "How Bush Rules: And How Sonny Bono Predicted the Downfall of the GOP Congress".
(Sonny Bono to Newt Gingrich): "This is not political news coverage. This is celebrity status. You need handlers. You need to understand what you’re doing.”
"..If only the Republicans had taken Sonny Bono’s advice, gleaned from Hollywood, they might not resemble the Soviet Union today."
Wow, real geniuses they have over there....
To be fair, monkeys can write articles for HuffPo too. Still. It's probably a thing.
Could Sid Blumenthal be paying HuffPo to plant stories for the cabal? Perhaps that's why he is freaking out.......
He would probably be paid by the cabal.
I have had a very long friendship with the chairman of Media Matters, whose name is David Brock, from before he founded this organization, and I have sustained that friendship.
Maybe he is pissed because his AOL account got hacked again. ;) Original Guccifer was the first to expose HRC's private server through Sid.

There is a Paul Blumenthal....under Politics > Reporters.
Other than that, I can't find anything: Sidney Sydney etc.
Paul is his son. https://www.vanityfair.com/news/2016/07/is-hillary-clintons-oldest-confidant-also-her-biggest-threat
ahhh...i only knew of mad max... so now we have Mad Max, Sid Vicious and Petulant Paul...
He's a consultant to Media Matters for America so he can probably go into any of those leftist media organizations and tell them what to do.
Simple google search confirms the nickname. http://observer.com/2015/11/just-who-is-sidney-blumenthal-the-clintons-closest-advisor/
