But the Democratic Party establishment (There is no Democratic Party establishment) Doesn't Care

Once again, we find that real Democrats do a better job of winning elections than do the DINO "Moderates", because if you stand for nothing, the voters are not motivated to support you.

This does not matter for the Democratic Party establishment (There is no Democratic Party establishment) because their goal of the party functionaries is to raise lots of money, spend lots of money, and get a cut of all that money so that they can buy a nice house and send their kids to private school.

To quote Upton Sinclair, "It is difficult to get a man to understand something, when his salary depends on his not understanding it."

The Democratic Party Pizzaburger Theory of Electioneering is: half the electorate wants a pizza, the other half wants a burger, so we'll give them all a pizzaburger and make them all equally dissatisfied, thus winning the election.

But no one wants a pizzaburger. The Biden administration's approach of letting the Warren/Sanders wing pick the antitrust enforcers while keeping judicial appointments in the Manchin-Synematic universe is a catastrophe in which progressive Dem regulators (who serve one term) are thwarted by corporatist Dem judges (who serve for life).

The 2022 midterms included enough races to start testing these theories – and, unlike traditional midterms, these races enjoyed high voter turnout, thanks to the unpopularity of GOP positions like abortion bans, book bans and anti-trans laws. Jacobin teamed up with the Center for Working-Class Politics, Yougov and the Center for Work and Democracy at ASU and analyzed those races. (PDF)

Their conclusion: candidates from working-class backgrounds who campaigned on economic policies like high-quality jobs, higher minimum wages, a jobs guarantee, ending offshoring and outsourcing, building infrastructure and bringing manufacturing back to the US won with a 50% share of the vote in rural and working-class districts. Dems who didn't lost with a 35% share of the vote.

This is not new information.  As Harry Truman noted, voters prefer a real Republican to a fake Republican.

But this will not matter.  The entrenched party bureaucracy cycles through the revolving door between party positions and for-profit consultancy, and they know where they get their money, so nothing will change.
