I really think that a majority of Democratic voters are either or both of:
-ideologically conservative but vote Dem because the Republicans are racist or otherwise too immoderate
-would rather see the Dems as "the adults in the room" than as doing uncouth or immoderate things to actually enact an ideologically-driven legislative agenda ("we go high when they go low")
If things were otherwise, I think Bernie would have won the primary.
I hate, and continue to hate, that “when they go low we go high” mentality. Is it mature to refuse to use strong rhetoric when the opposition gleefully deploys it? It’s a losing, demoralizing thing. Whenever I heard it, it felt like a rationalization put forward by those afraid to actually try to win. Not very mature that, IMO.
More generally, though, it’s a time of uncertainty. The narratives people have built about what life is supposed to be, many have seen enough contrary to those narratives to abandon them. On economic matters, social ones, people don’t know what the future is going to look like. Old narratives fail, people look for new ones. It’s a ripe climate for swift change.
One young, handsome charismatic leftist candidate with a talent for sales could very well come along and change the minds of the people spoken of in quick time. It’s the age. Present assumptions about what people want are shaky, because I don’t think they themselves know what they want beyond a most general desire for greater well-being. Obama followed this approach, to great success(even if he couldn’t always translate it to policy).
Selling redefined, forward-facing policies, if done well by a good-looking face, isn’t out of the question. What people think they want these days is moving fast.
