Also on Sunday, the conservative activists and Trump supporter Amy Kremer claimed on CNN (again, without proof) that Clinton suffers from CTE, the degenerative disease caused by repeated blows to the head that some former NFL players have been found to have suffered. The influential Drudge Report has often made space for stories suggesting Clinton is unhealthy. Breitbart, the Trump-adoring conservative website whose CEO Steve Bannon recently became CEO of the Trump campaign, has also been a central purveyor of rumors.

Trump has gotten in on the act, dog-whistling toward the health worries. He has warned that Clinton “lacks the mental and physical stamina to take on ISIS, and all the many adversaries we face,” and there was this peculiar tweet last week:

(Trump has said in the past he sleeps for only four hours a night.)

Concerns—or more frequently concern-trolling—about Clinton’s health dates back to 2012, when she reportedly fainted while suffering from a stomach virus and sustained a concussion. After the injury, doctors found a blood clot and prescribed thinners. She later appeared before a Senate committee discussing the Benghazi attacks wearing special glasses.

In June 2014, Andrew Stiles, then of the puckish conservative site the Washington Free Beacon, wrote a satirical post questioning Clinton’s health, based on a People cover in which the former secretary of state clutched a patio chair, which he claimed resembled a walker.

“Notice the subtle placement of the word ‘grandmother’ at the bottom of the page, next to what a layperson might reasonably assume to be an old person’s walker in Clinton’s hand,” Stiles wrote. “Then there is the juxtaposition of a graphic celebrating the life of [recently deceased] Brady Bunch star Ann B. Davis. Taken together, these aspects of the cover raise troubling questions about PEOPLE Magazine’s political agenda.”

Stiles then wrote a follow-up post with a photoshopped image of Clinton using a walker. Both posts were tagged as “parody” on the Free Beacon. He would go on to write the recent Heat Street post, a series of images showing Clinton leaning against pillows with exaggerated arrows pointing to them.

These satirical posts are relevant not because they are especially dangerous or unusual, but because they are so indistinguishable from the innuendo of folks like Giuliani, Jones, or Kremer. In fact, lots of news stories treated Stiles’s latest post as earnest, and Drudge also featured it. “There are lots of idiots on the internet, unfortunately,” Stiles wrote in a message. He noted that the Heat Street post never actually makes any assertions about Clinton’s fitness, although “people might assume that based on context of other, more earnest, nonsense.”
