First, I wasn't talking about the Democrats, I was talking about the Left. I don't really see much of a connection between the two. That said, I urged everyone to vote for Clinton and still think that we'd be better off had she won (the judiciary, in particular, wouldn't be as bad). The sad reality is that there were two choices, Trump or Clinton. That had nothing at all to do with fighting fascism except in the sense that Trump was way, way, WAY worse on the issue.
Second, yes, people have liked many leftist ideas for a couple of decades now (at least, I'm just going on the polling I've seen over the last twenty years). But here's another sad reality: people don't generally vote for ideas. They vote for people. Had Obama been able to run again, I think he'd have won, and if Sanders had challenged him he wouldn't have done very well, because Obama had high positive numbers. He did well against HRC. Some were inspired by his ideas, but most just liked him. I know a Republican woman who hated Clinton but loved Bernie. She even voluteered for him. The exact same policies, coming from someone else, wouldn't move her at all. I suggest that she's not unique in the least. I truly believe that she's the standard. It's what psychologists tell us--people are more impressed with a good story than with facts. It took me a long, long time to realize that I was an outlier, because I prefer facts. That led to many frustrating converations until, finally, I understood that people just don't care about such things. Far better to get them angry about something than convince them of the rightness of your position.
Which leads me to fascism: Trump is a symptom, sure, but he makes people angry, and that's something that can be used (and IS being used by march organizers). (Also, it might be good to consider how the far right has been so very successful at creating so very many "symptoms." That's what I mean about organizing.)
What you're talking about is a single instance. Trump beat a deeply flawed candidate. What I was talking about is why Trump was the alternative. Why was a guy who was the darling of the KKK the alternative? Because fascists organize. They support each other. They share a common enemy, and that's something the Left doesn't stress at all, prefering to snipe at each other over obscure points of ideology or condemn one another because of a disagreement on one issue. That way lies defeat, and considering the Left has had no power in the USA since the early Seventies, defeat is all two generations of Americans know.
