That is all well and good, but you arent saying the DNC was "biased" you are saying they cheated and rigged it. (yes you are stop it) None of what you posted shows any of that. It shows that the many in the DNC didnt like Bernie, which was something we knew long before the Primaries. Hell we knew the same people in the DNC supported Hillary over Obama for much of 2008...
If anyone else was posting stuff like this to back up a claim like yours you would be accusing them of confirmation bias. (like all Conspiracy Theories) You are taking the fact that Bernie was not well liked by people in a Party he was not a member of (and spent a lot of time deriding) to mean they in some way hamstrung his campaign. That isnt what happened though. Bernie had no issues raising money, campaigning, being in debates or getting his message out there.
Unless you can show me how Donna Brazille and DWS convinced 70-90% of Blacks over the age of 30 to vote for Hillary (
source ) then all of your conjecture is moot. Unless you can tell me how any of what you posted stopped Bernie from winning over women your point is even more moot. And unless you can tell me how it prevented Bernie from winning over anyone over the age of 44 (and they were even 30-44 for the most part) your point is as empty as Flaggy's "girlfriend". (

Here is a Source I Trust a Bit Less But Breaks it Down Well
I am sorry but Andrew Yang has a better argument for being screwed over in any capacity than Bernie Sanders does. (and his is a joke as well) Bernie always had an uphill battle for much of the reasons you posted. Most of them were discussed here BEFORE 2016

I, as a Bernie supporter, even said all the stuff your "evidence" is saying long before the Iowa Caucus. (and said the same as an Obama supporter in '08) But Bernie didnt lose because the DNC insiders tipped the scale, he lost because he wasnt as good of a candidate as Obama was. Maybe he was too White, maybe he is too Jewish, maybe he was too old, maybe it is hard to run as an "Outsider" when you have been in D.C. since the 1920s...I dont know but he didnt resonate with a lot of them and it wasnt because he was a Socialist. Right now he isnt being held back by any of that and he also seems to be running a better overall campaign anyways.
Getting off the "Persecution of Bernie S" for a second...the demographic breakdowns of this election and the voting patterns are kinda all over the place. I never buy into the "Brokered Convention" bs the media plays up but I really kind of think we are headed there right now. None of these candidates are striking a chord overall. Each has their loyal following but no one seems to make any headway into adding to it. I can see a real path to 3-4 staying in longer than needed and no one getting the plurality.
This could get ugly, but **** if it wont be fun to watch. If that is then this guy just became more powerful:
