I mean democrats categorically support unions, support reproductive rights, support protecting the environment… They do have a platform that isn’t “not Republican”. It’s just that republicans know their platform (project 2025 really) is so wildly unpopular they have to focus not on that, they have to focus on tearing down the opposing candidate.
In terms of helping the working class: taxing the wealthy and wealthy corporations more will help the working class. Improving access to low cost / affordable healthcare will help the working class. Having strong unions will help the working class.
I like how people act like not voting is some mega message to people. Like guys, most of the population already doesn’t vote. You’re not sending any message when you don’t vote. You want to move California left of this guy? Go vote for the most left candidate. Vote in the primaries for the most left candidate. You get where you want to go with solutions to the problems you have by voting, not by not voting.
