Having seen his posts afetr months of lurking, I'd say maybe 5% if he is lucky. Honedstly he is at odds with most of the Demcoratic party. That is both its moderate and liberal wings.
I would best classify him as "libertarian" socialist.
No, not a socialist at all. I advocate redistributionist Keyensianism, but in case you didn't know it, that is built on the same social heirarchy known as Capitalism. The Owners still get the top position, they just have a little bit taken away to moderate inequality.
