Suppose for the sake of argument that Donald Trump rules the Electoral College and he returns as President. A clock started ticking yesterday and will still be ticking as Trump goes into his seventh year as President. All of a sudden, the chloroquine clock rings, and it's time for chloroquine retinopathy. Trump's eyesight will be considerably impaired, and if his doctor doesn't get him off the stuff, Trump will go blind. That's why it is of limited value for lupus and rheumatoid arthritis; you can't take it for more than 4-5 years. So, I hope his doctor grows a pair in the next few years, because even if a vaccine is found in 1-2 years, you know that Trump will keep taking "what works."
