Good question. The infiltrators have corrupted so much of it, and many even call themselves progressives when they are anything but. I recommend the Green Party or check out many of my posts. I like to post old-left stuff except for the climate change carbon tax scam and/or scientism stuff. I think you'll also find a LOT of anarchists/voluntarists also lean old-left. There are some AnCap / Libertarian folks I might post on occasion but I usually find them too selfish and/or narrow minded to promote much.
