Might as well vote for the PSL or Green if you happen to be free on election day. Just don’t waste your time defending the two genocidal capitalist parties. Spend it organizing and taking direct action.
For the left, electoralism is only good for some advertising. A capitalist system won’t let socialists come to power even if they somehow manage to win like we’re seeing in France with Macron right now. Liberals will side with fascists long before they ever think about looking left, as they always have historically.
