You cannot vote revolution into power in a liberal system. Full fucking stop.
The most important role that he plays is moving the Overton Window, that alone is much more important than anything he actually achieves. Just him refusing to “recognize Israel as a Jewish state”, claims he doesn’t like capitalism and literally just being Muslim has shifted the narrative over what is permissible in the eyes of normies. And NYC is front and center in the US, this isn’t Hoof Hearted, Kansas.
So I’m willing to say his election is of massive importance, even if what he actually accomplishes is lackluster.
You’re subject to the conditions of the world/country/city etc that you live in. Don’t believe capitalist propaganda, communism isn’t a vow of poverty. In the US the conditions still aren’t at the level (but things are rapidly moving) of the usefulness of a Vanguard Party but the Empire is punch drunk with multiple major wars lost, a declining economy, and a government increasingly desperate to keep things together through force.
For now, educate yourself and link up with entities that seek relief for what is possible in this poisoned nation.
