A very good summary, IMO, of the current 'party brand above policies' dilemma that we have:

"The evidence suggests that the party that commands a built-in and growing demographic majority and that won the popular vote in seven out of the last eight presidential elections simply does not want to press its advantage. Why not? I propose that key members of the Democratic establishment are more concerned with disciplining and containing the party’s left flank than with maximizing their power as such and view the idiosyncrasies of the federal system—and the advantages they give the Republicans—as potent tools for achieving those ends."

The Parties Decide

MMT Economist Steven Keen often says it we will get change in understanding of fraudulent neoliberal economic theory one economics professor at a time.

I wonder if the current 'hostage politics' will die with one boomer, and to some extent genX's, death at a time. The flexibility of thinking about politics seems to be locked into these demographics. When they are no longer the dominant voting cohort then, perhaps. I'm just doubtful there's enough time.
