To be fair a lot were clamoring behind Bernie Sanders. But Hillary bent the DNC to do some fairly corrupt shit and so you got Trump. The democrats are still trapped by this neolib-technocrat-west-wing fantasy-land where the best person at debating wins regardless of the fact they don’t actually stand for anything.
85% is more accurate. The 15% are the 1% plus their enablers/support/wannabes.
I agree, such statements are underappreciated. But I'm not running for office so popularity isn't really my concern. It also doesn't help to be silent when faced with the current status quo. Change is painful; saying what needs to be said even more so.
The specific actions the DNC took to cause Bernie to lose includes:
1) They chose to put the debate between Hillary and Bernie at MIDNIGHT so people wouldn't watch the debates. It was at the start of the primaries when people didn't know much about Bernie so the DNC decided that nobody watching the Democrat's primary debates helped Hillary
2) In the debates, they gave the questions to Hillary before the debates. The DNC controlled debates gave them to a CNN person who would give them to Hillary
3) The DNC owns the decision about Super delegates. Super delegates == ignoring one-citizen-one-vote
4) Arizona greatly reduced polling stations. With 3+ hour waits, people gave up. The DNC knew that Hillary voters voted at a higher ratio on mail-in-ballots, so it skewed to Hillary.
5) The California level had Bernie votes made in a way that they were all not counted:
In California 2016 election, "NPP" (Non-party voters) the election committee training pole workers to give them "provisional ballots". All of those NPP votes ("provisional ballots") were thrown away. The only NPP voters that could be counted were "Democratic cross-over ballots", but they they poll voters weren't trained that way. Bernie Sanders votes where thrown away. In California Bernie had 61% in polls against Clinton, but then lost. .

I saw some defenses of Hillary's actions (i.e. the 'bailout' was an ultimately good act, done to strengthen the DNC, proving her commitment to defeat Trump and protect progressivism etc.) which doubles as a cynical defense of Putin/Russian oligarch money in tech (it keeps Silicon Valley running and adding to US employment numbers)
They advertised her superdelegate lead before the voting even began. They leaked debate questions to her in advance of the event. They smeared Bernie with unfair accusations and labels. They worked directly with big media outlets to either deny or put out negative coverage of Bernie. The Washington Post put out 16 negative stories on Bernie in one day. There was unregistering of progressives in New York, and a botched delegate counting process in Nevada. They reduced the number of debates before the first primary by at least a third. DNC leads got caught actively cheating, leading to their resignations - Debbie Wasserman Shultz and Donna Brazile. They actually used the excuse in court that the Democratic party is private and has no legal obligation to run fair elections, and could select in a backroom smoking cigars if they wished. They actually said on national television that superdelegates served the purpose of preventing grassroots candidates from winning. I could go on and on. All of these things are easily verified. I can give you more if you'd like, with references.
I don't think you can point at a specific action, but the leaked (Podesta, I think) emails seemed to show that the DNC was working to help the Clinton campaign to the detriment of Sanders during the primary. This lead to the resignation of Debbie Wasserman Schultz from the DNC chairman position.
Later, it turned out the Clinton campaign had essentially taken over the DNC far in advance of the primary results which is highly unusual, to the say the least. [1]
She won due to superdelegates and DNC corruption as well as media capture. The fact that Bernie did as well as he did in the face of this is a testament to how bad of a candidate she was.
Why should the superdelegates have flipped their votes against the popular vote? This makes no sense.
The only way Bernie would have won is if he convinced superdelegates from states that came out for Clinton to go against the popular vote in their state and erroneously vote for him. He still would have lost with no superdelegates, or if their votes were awarded to their state's primary winner.
