if m4a did happen to land on a president harris’ desk for a signature, i have zero doubts about her signing it.

Why do you think that?

From the second link:

Sanders immediately challenged Harris’ description of her plan as proper Medicare for All.

“I like Kamala. She’s a friend of mine, but her plan is not Medicare for All,” Sanders told CNN ahead of the debates. “What Medicare for All understands is that health care is a human right and the function of a sane health care system is not to make sure that insurance companies and drug companies make tens of billions of dollars in profit.”

A senior policy adviser to Sanders called Harris’ rejiggered plan “bad policy” and “bad politics,” warning it “vastly expands the ability for private insurance corporations to profit from over-billing and denying care to vulnerable patients who need it the most.”

And from the same link, I'm going to agree with the Trump campaign on this one:

“Kamala Harris’ spokespeople are once again alleging she has flip flopped on her positions – this time saying she no longer supports socialist Medicare for All,” Trump campaign spokeswoman Karoline Leavitt said on Wednesday, calling on Harris “to explain why she is running from every liberal policy she has ever supported.”

Yeah. I'm gonna vote for her, but no part of me thinks I'm going to see police reform, m4a, etc from her, and it makes me sad because these are long cycles, and I have to imagine I'll be near dead of old age before we've got much chance of the kind of change I feel like we had the chance for coming out of 2020. She portrayed herself as a lot more progressive in 2020, and plenty of people called her on it then when considered against the backdrop of her pre-Senatorial record.
