You might have a valid point if 9% of Democrats didn't vote for Trump. Maybe then you could legitimately blame Clinton's loss on the Bernie babies.. Are you aware a higher percentage of Sanders supporters voted for Clinton in 2016 than Clinton supporters voted for Obama in 2008? In other words, you're speaking establishment, propaganda, nonsense, directly out of your ass.
It ain't us that lost you the election, it's you. You chose to abandon the middle-class and court conservative donors, BRILLIANT! You chose to shit on Sanders supporters and ignore their dire warnings. BRILLIANT! You thought facing Trump was a slam dunk, BRILLIANT!
Clinton was your turn, now it's our turn. That's the fight. If establishment Democrats hand the reins over to actual progressives, then actual progressives will win, people like you will lose influence and power. It's actually better for people like you, politically, to give progressives just enough power to make it seem like they have control, preferably during a Republican majority so they can obstruct everything. Then the establishment types can come out and rehash the same old arguments against the progressive wing of the party and continue business as usual. That's why both Chuck Schumer and Harry Reid endorsed Keith Ellison for DNC chair.
