Hillary 2016 was the worst thing to happen to the Dems because it not only doomed us to Trump but alienated millions of working class, low trust, young, and progressive voters from the party, possibly forever, by treating those who didn't like it with sneering, vicious contempt.
Bernie’s run in 2016 was perhaps the worst thing to ever happen to the Democratic Party because it have a bunch of lefties false hopes followed by an incredible persecution complex.
