One thing that stands out to me is how ubiquitous the notion that Democrats *should* be winning by big margins, and *should* have a durable ruling coalition, is across different ideological factions in the broad center to left coalition.
Now everyone has their different views about What They're Doing Wrong, etc.. Lots of the critiques are good and draw blood, and have merit at the margins. And, look, I get that GOP governance has been an absolute horrifying deadly disaster across two administrations now!
And but also: It's a big, complicated country with lots of conservatives! We're very closely divided, politically. I've noticed, interestingly enough, conservative growing more resigned to that & putting their faith in instutions they can control: state government in red states..
as well as maximizing the *considerable* leverage the Constitution gives to minoritarian institutions - the Senate, SCOTUS, the electoral college -- to rule with 46-48% of the country.
I'm not saying Democrats or liberals or lefists should just resign themselves to these anti-democratic institutions or to narrow national victories and big losses in larger parts of the country - quite the opposite.
But it's worth really reassessing the analytical foundations of the idea that there is some big, enduring New Deal-level Democratic coalition out there for taking if Dems would just Do It The Right Way.
