I’ve been asking that question for years and never gotten a good answer.

Who have you been asking that question to? Yourself in the mirror? Your Teddy bear late at night? I have an extremely hard time believing that you have spent more than 30 seconds trying to find the answer to this question considering this is all very public knowledge. Despite the mainstream media trying to downplay this issue, the truth isn't that hard to find.

citing news articles claiming the DNC supplied Hillary with all of the debate questions ahead of time and planted audience members to ask Bernie weird questions, citing wikileaks emails

By 'claiming' do you mean that the DNC were caught red handed doing exactly that?

Did the article also happen to mention that the lawyers for the DNC argued to the Judge that the language in the DNC's charter about being impartial and evenhanded is just "political promise" (aka, a lie) and that they are under no obligation to be impartial? That the DNC has 'every right' to choose who they want as the candidate? There is absolutely no reason whatsoever to believe that isn't the way the "Democratic National Committee" operates to this very day.

the Bernie Sanders Campaign team dispute any such claims that DNC’s Brazile was biased.

First of all Bernie is a real one who has class and was more focused on defeating fascism than getting justice for himself. Unlike the Crooked DNC, he puts what's best for the country ahead of his own interests.

The claim wasn't that Brazile was biased. It was Debbie Wasserman Schultz, Hilary Clinton, and other higher ups in the DNC that colluded against Bernie. DWS resigned as the Chair of the DNC specifically because the email leaks showed party officials conspiring to sabotage the campaign of Senator Sanders. DNC CEO Amy Dacey, CFO Brad Marshall, and Communications Director Luis Miranda also resigned in the wake of the controversy.

In fact it was Donna Brazile who replaced DWS as interim chair of the DNC that uncovered further evidence of tampering by the Clinton campaign and related that info to Bernie- who took the news like the chad he is.

It’s all just Hillary’s emails, bruh

Of all the liberal hot takes this is the smoothest brained take yet.

First of all you are conflating the Hillary Clinton email controversy the with the 2016 Democratic National Committee email leaks.

Secondly the reason that "But her emails!.." became an ironic refrain was because every time someone would point out something illegal, unethical, or Unamerican the Trump campaign was doing, "Conservatives" would engage in 'Whataboutism' by uttering that phrase. Not because Hillary wasn't caught doing some extremely shady shit- she absolutely was.

Accepting that reality is the way forwards.

Ironic. I'll make you a deal. Once you learn what the reality of the situation actually is and accept it- we can work on moving forwards from there. How bout that?

It sure would be nice if people like you could learn how to use search engines on your own. I feel like I should get paid to do this for you. I wouldn't even bother if I didn't think there were other libs reading this who were likewise confused and might find this info useful.
