I listed those things because those are the things I see being prominently debated. Also, all of the states with paid parental leave, and other laws good for the general public such as assisted suicide and marijuana legalization, are in Democrat states, for what it’s worth.
But at the end of the day, the root obstacle is voter non participation from those that would benefit the most, and voters who absolutely will not accept higher taxes, especially for any type of wealth redistribution such as paid parental leave, healthcare, education, etc.
I doubt you can group all those people together, and remember, you don't know them.
You listed a lot of right issues to imply that the left is the only side fighting for it, which is not true.
