I remember voting for Sanders a couple different times
Biden did quite a bit for the working class, although quite a lot more would be fuckin fantastic. But I do get your point. I feel like maybe you are confusing “get to vote for” with “get to have on a silver platter without needing to play on the tilted table that is US politics and actually get the dude or dudette elected”. I don’t think there has ever been a country where the ruling class will let go of power and give the people a fair shake just because they stand up and say “better candidates pls I don’t like these ones.”
In other words what’s your alternative, just give up and wait for things to get worse until we all starve or go to the camps?
