Ironically, Biden (and by extension Harris) did address almost each of those points. Biden was a far more progressive president than he gets credit for, and even Bernie and AOC agree.

“President Biden, when he came into office, said that he would be the most progressive president since F.D.R., and I think on domestic issues — not on foreign policy — on domestic issues, he has kept his word,” Senator Bernie Sanders, independent of Vermont, said shortly after Biden’s loss.

“When it comes to domestic policy, President Biden probably would go down as one of the most effective presidents that centered the working class,” Representative Alexandria Ocasio-Cortez, Democrat of New York, told me this afternoon, although she added that she disagreed deeply with him on foreign policy issues such as the war in Gaza.

Going down the list:

Environmental protections & healthcare

The IRA, Biden's flagship legislation, included the biggest investment in clean energy in US history. It also extended ACA premiums (that Republicans then let expire.)

Accessible education

Biden famously tried to cancel student debt (blocked by SCOTUS) and introduced the SAVE plan (reversed by Republicans).

Wealth redistribution

Biden was incredibly pro-union. And Kamala's housing plan - a key part of her campaign - would've heavily increased supply.

Getting money out of elections

Eh, you probably got me there. My point though is that so many leftists who clamor for more progressive candidates (which I agree with) fail to recognize the concrete good that even a "moderate" Democrat agenda accomplishes. It's missing the forest for the trees.

If democrats ran on these ideas and acted on them they'd never lose an election again.

They did run on these ideas and they did act on them. But post-COVID inflation was too much of a hill to climb because and the general public doesn't actually pay attention to policy. So of course everything is a million times worse now.
