Yes, solarpunk is political. And while capitalist would-be-lords try to buy out elections, it is important you oppose them by voting. Locally, vote for candidates who support solarpunk values such as public transit and green infrastructure.
If you, like me, have the misfortune of living in the USA with its death economy, we need to vote and register others to vote for a candidate who is part of that bad system: Kamala Harris. A corporate Dem is at best a bandage for the open wound of fascism. Harris is not a solution. But if you don’t vote for her, that wound is going to get even more rotten.
