He is running a propagandistic campaign that seems to be more about 'bending the stick' of public perception of what is mainstream political/economic thinking in North America.

But for myself, as someone who would call himself a kind of Marxian socialist, I wish he'd stop calling himself a socialist. He is doing both himself (at best a Euro-style social democrat) and socialism a disservice.
