On the front portico of the future Trump Presidential Library (which will display his tweets and ghostwritten books), this credo for the ages should be chiseled in stone:

WHAT DO I KNOW I’M NOT A DOCTOR

That’s what the quack said during his Sunday propaganda spew, while hyping the purported miracle drug that he hopes against hope will rescue him from the deadly health and political crisis of his own making. In the words of one former Trump official, the fake president’s desperate embrace of hydroxychloroquine exposes his “overwhelming desire for a silver bullet to make it all go away.”

His hunch that a controversial anti-malarial drug will somehow cure the coronavirus pandemic, despite a dearth of scientific testing, is the quintessential proof of his fraudulence. This guy makes the Wizard of Oz look like Hippocrates.

You know how doctors endeavor to “first, do no harm”? That’s for pansies. The MAGA medicine oath is, “What do you have to lose?”

Trump said that on Sunday, too. Hydroxychloroquine has been around a long time, to help treat malaria and lupus. But as a treatment for the coronavirus, and, indeed, as a coronavirus preventative, Trump thinks it will be “a very special thing…It will be wonderful. It will be so beautiful. It will be a gift from heaven, if it works.” But of course it will work. Why? Because “a lot of people are saying” it will work.

Which “people are saying” that? Laura Ingraham of Fox News, for starters. She reportedly flew down to D.C. to tout the drug in person, bringing along two medical talking heads from her Fox show. Rudy Giuliani, fresh from his Ukraine mission to frame Joe Biden for nonexistent corruption, has also told Trump he likes the drug, which tells you all you need to know. White House sources have told The Washington Post that Trump has also heard thumbs-up anecdotes from “Wall Street guys, real estate guys” in New York. And some big-shot Republican donors have financial stakes in a French firm that makes a brand-name version of hydroxychloroquine, but I’m sure that has no influence on him whatsoever.

But the list of people who are not saying the drug is a miracle (quite the opposite, in fact) is topped by Dr. Anthony Fauci, the government’s lead medical spokesman on the coronavirus crisis, and Food and Drug Administration chief Stephen Hahn, who isn’t comfortable endorsing a drug that has not been tested in credible coronavirus trials. One of the only studies conducted thus far had 62 patients; another had 30; another had 20. (The latter study, in France, eliminated three patients who had to be transferred to intensive care, and one who died.)

Science is supposed to go like this: first you test a drug in valid large-scale research, and if it works over time, then you approve it. But Doctor Quack, who thinks he knows more than Fauci, shared this insight with the nation on Sunday: “I really think they should take it.” He’s even amassing a national stockpile to help Americans take it.

The danger, of course, is that the suckers who hail Trump as the font of wisdom will duly obey – and remain ignorant of the side effects that Trump has failed to mention. According to one public health expert, those range from “vomiting and headaches to instances of psychosis, loss of vision, and even sudden cardiac death.” The drug messes with heart rhythm. In some of the most serious coronavirus cases, the disease can cause heart infections; in those cases, Trump’s miracle drug could be the coup de grace.

On another front: Some Americans suffering from lupus surely voted for Trump in 2016. I’m wondering how they feel about him now. Thanks to Trump’s touting of the drug, Americans are starting to hoard it and lupus sufferers are having a harder time getting it for their legitimate reasons. But fear not, lupus people! Trump says that people with lupus can’t get the coronavirus. How does he know this? Because he knows what he knows.

Here’s what he jabbered on Saturday: “There’s a rumor out there that because (hydroxychloroquine) takes care of lupus very effectively, as I understand it, and it’s a, you know, a drug that’s used for lupus, so there’s a study out there that says people that have lupus haven’t been catching this virus. Maybe it’s true; maybe it’s not.”

By the way, there is no such “study out there.” This is how far and how fast we’ve fallen as a nation – listening to medical quackery from a sick puppy.
