Weirdly enough he does seem to have some True Leftist supporters based on DU, who seem to think the attacks on him are all part of some Big Pharma/Monsanto conspiracy because he supports GMO labeling and promotes "non-traditional" medicine. No doubt he has plenty of support amongst Alex Jones types as well seeing as how caught up they tend to be about the same stuff. Such an alliance here isn't surprising, but it is a little odd to see these types rallying around someone whose primary fanbase is middle aged housewives.
Unfortunately, there's a lot of people who are willing to believe ridiculous conspiracy theories about science/medicine once you substitute "self-promoting academics" out for "corporate-funded academics." Vague, ridiculous paranoia is hardly exclusively a conservative thing.
