I don't consider myself a "progressive" but I agree with your priorities - job security, better wages, and pro-family policies. Infrastructure and healthcare. Pre-Obamacare, most personal bankruptcies were due to uncovered health emergencies. Putting a little money into that, helps the economy as a whole.

I don't think the Dem Elite will ever let working class people in the door. And that is one of the biggest reasons why (imho) it is not worth voting Democrat at this time.

I don't think expanding the Supreme Court would work in the Dem's favor. Because as soon as Repubs get power again, they will do the exact same thing. Which will be as early as 2024.
