The point is, it's a loaded word used to describe what you don't like, more than it is an actual recognisable political stance.
The US communist party is a joke obviously, their endorsement or lack of the same means nothing.
As for Hillary, she had some ambitious plans for health care and education while she was the lady macbeth behind the man, amd I applauded them.
Nevertheless, to me, her bid is only one step away from the nepotism of the Bushes. Only shows how deeply insular the political power base has become that in so enormous a country, the latest 4 presidents could wind up being very closely related indeed.
