The weekend wobble was treated by some political rivals and online antagonists as validation -- proof positive that the Democratic nominee was unfit, in the most literal terms, for the presidency.
A shadow campaign pushing rumors that Clinton is hiding a grave illness to protect her White House aspirations has existed for years, but only found a voice and high-profile champions during the last few months of this general election contest.
Even as Clinton took a brief leave from the stump -- she is set to resume travel
on Thursday --
her campaign wrestled with legitimate questions about a lack of transparency during the Sunday scare, the rumor mill churned apace.
Donald Trump, who has considerably been less open about his health, was mostly restrained in the aftermath -- though he did couch his well wishes with some goading analysis, saying on Monday: "I just see what I see -- the coughing fit was a week ago, so I assume that was pneumonia also."
Or not. Facts have rarely gotten in the way of dubious suggestions about Clinton's health. In a letter
released Wednesday, her physician made a point of stating that the candidate "is in excellent mental condition."
Here -- quite apart from any legitimate concern stemming from her recent illness -- are a few of the more ludicrous and resilient theories:
Whatever might be wrong, it's now being covered up by ... a body double!
In the aftermath of the Sunday incident, web sleuths turned up a series of images they believe show the Clinton campaign used a "body double" to reassure the public and trick the press. Collected under the hashtag, #HillarysBodyDouble, photographs of the candidate before and after she fell ill are being compared, as features like her nose, ears and fingers are plotted side-by-side for examination and debate.
"Shocking claims are coming forward about a body double and who really emerged from (daughter) Chelsea's apartment [on Sunday]," blared
the right wing Madworldnews.com.
The writer goes on to ask: "Was it (longtime Clinton impersonator)
Teresa Barnwell outside Chelsea's apartment yesterday, hired to salvage Hillary's campaign as it was imploding after the collapse?"
Barnwell responded to the suggestions -- spreading across social media -- that she had stood in for Clinton with a tweet of her own.
"I'm in Los Angeles today," she wrote. "Not in NYC!"
Clinton is sick ... because someone, perhaps a Russian agent, is poisoning her
Dr. Bennet Omalu, the forensic pathologist whose role in highlighting the aftereffects of head trauma on former NFL players was dramatized by Will Smith in a recent film, weighed in with his own theory on Sunday night.
"I must advice (sic) the Clinton campaign to perform toxicologic analysis of Ms. Clinton's blood," he tweeted. "It is possible she is being poisoned."
Omalu is, on the face of it, a more credible source and discerning eye, but, though a doctor, he has not examined Clinton. Rather than expand on his medical reasoning, he followed up a little less than an hour later with a cryptic tweet: "I do not trust Mr. Putin and Mr. Trump. With those two all things are possible."
Though Putin's government has been implicated in the 2006 poisoning death
of a former KGB operative in London, there is no evidence -- and nothing in any of Clinton's medical notices, provided by her physician -- to suggest anything of the sort is at play here.
Clinton has suffers from post-traumatic 'dysphasia'
The bulk of the most prominent healther conspiracies
center on Clinton's December 2012 concussion, suffered after she fainted while sick
with a stomach virus.
Clinton's injury caused her to postpone planned testimony on the Benghazi attack, leading right-wing skeptics to accuse the then-secretary of state of coming down with a "diplomatic illness"
-- or faking it. Those whispers died by the end of the month, when doctors discovered a blood clot
in the vein behind her right ear during a follow-up exam. Clinton was treated with blood thinners and she testified to Senate and House committees a few weeks later
, on January 23, 2013.
Multiple currently circulating theories attach themselves to the 2012 fall, including one pushed by Trump spokesperson Katrina Pierson, who in August offered matter-of-factly that Clinton was suffering from dysphasia
, a neurological disorder that complicates speech and language comprehension due to brain trauma or disease.
"What's new are the other reports of the observations of Hillary Clinton's behavior and mannerisms," Pierson said during an appearance on MSNBC, after being asked why the campaign was indulging the rumors. "Specifically with what you just showed in those previous clips, as well as her dysphasia, the fact that she's fallen, she has had a concussion."
Meanwhile, a Fox News contributor Dr. Marc Siegel -- who himself has noted that he is "not a neurologist" -- pushed a similar line.
"I saw the same video you saw, and I'm wondering about a word called 'aphasia,' where you're searching for words, you suddenly lose those words, and that can be the sign, again, of some kind of traumatic brain injury or the after-effects of a concussion," he said on pro-Trump commentator Sean Hannity's show.
Brain damage, seizures, Alzheimer's and Parkinson's disease
The list of purported maladies goes on.
Karl Rove, the former top adviser to President George W. Bush, suggested in 2014
Clinton had been "wearing glasses that are only for people who have traumatic brain injury," while assorted right-wing sites and Twitter trolls have suggested she is prone to seizures
-- a belief that sprung a new theory claiming a Secret Service agent's flashlight was really an "an auto-injector with Diazepam."
Other have mused that she could be suffering from Alzheimer's
or Parkinson's disease
The conservative Powerline blog featured an anonymous letter on Sunday, from who it described as a "prominent internist," suggesting Clinton's pneumonia was related to Parkinson's:
"I raise this second possibility," he wrote
, "because of Hillary's history of neurological illnesses (blood clot in brain, concussion), hints raised on the internet in Wikileaks documents and by others that she may have a neurological disease like Parkinson's, and her by now well documented history of recurrent coughing fits. This second possibility is that she has an aspiration pneumonia."
The first possibility, stated at the top, was that she simply had contracted the illness, like any other "healthy person living her usual life."
Others, if you feel like further plumbing the depths of ungrounded theories, include: Lupus
and "imminent heart failure"
