I literally do blame the Democrats for Trump, and if you don't, you weren't paying attention.
Plenty of us were critiquing Clinton's campaign on those merits and were consistently talked down to in shocker the same way we're being talked down to now. Shocker, she lost. I remember saying a few weeks before the election "We're about to get Brexited." I put my vote down for Clinton, because Trump is fucking insane, and that was clear before he was President. It was clear in the fucking 1980's.
Being able to critique our leaders is supposed to be what is the difference between us and conservative voters. They're the cult who unquestioningly believes all the bullshit that comes out of Trump's mouth and diapers. I find it weird that people think we should be more like them in regards to our leaders like that would be a good thing.
Donald Trump entered a wide open primary with 17 other candidate. Jeb Bush, Ted Cruz, Marco Rubio, Scott Walker, Ben Carson, and John Kasich all had either the lead or second place in early polling at one point or another. We can laugh at them now, having seen what Trump did to them, but at the time rach was a party leader and legitimate contender.
Trump was viewed by the left as a disruptor, an agent of chaos, and most thought he was a clown with zero electability. He would say and do outrageous things, and made the GOP look silly in comparison to the DNC's coronation of Hillary.
Every news article about Trump got clicks. Every tv outlet that talked about him saw ratings rise. He was fucking everywhere in that summer, and he barely had to spend a dime. When he started rising in the polls, and the donations came in, Democrats thought it was the funny shit they ever saw. Independents in open primaries like New Hampshire were being told to cast a ballot for Trump, because wouldn't that just be hysterical if he won.
