"Jill Stein is an anti-vaxer" is, ironically enough, an example of left-wing (or at least pro-Dem) fake news - the article you linked even links to the Snopes article debunking it: http://www.snopes.com/is-green-party-candidate-jill-stein-an...

Amanda Marcotte claims that the Snopes article is attacking a strawman because "the accusation is not that Stein herself is personally anti-vaccination. The accusation is that Stein panders to anti-vaccination crowd" - but as your comment demonstrates, that isn't true. Indeed, her article and similar articles try hard to leave readers with this false impression, twisting Stein's argument that we need to restore public trust because vaccines are a vital public health tool into "sowing doubts about vaccination safety". If claiming that "Dr. Stein uses a common anti-vaccine dodge" isn't claiming that she's a secret anti-vaxxer, then I'm a chocolate teapot.

I suppose those candidates are either simple minded or have cynically spotted a 'previously ignored voting group'.

Heaven forbid one of them end up in the white house.
