Finally, finally, tonight, the presidential debate live on cable TV, CNN. If you have cable and plan to watch, what are you thinking? What are you hoping to see and to hear? Like millions of people around the world, I’m hoping to see and hear if Trump and Biden are healthy and clear-headed enough to do the toughest job in the world? Donald Trump is 77 years old. Joe Biden is 81. Both of them may be too old to do the job the way they’re saying they’ll do it. Each of them is insisting he’ll do it better than the other, and their so-called independent doctors are being instructed to deliver that message. In a three paragraph statement eight months ago, Trump said his doctor said his cognitive exams are exceptional but said nothing about what was involved in the exams. About other matters of candidate health, Biden’s press people say Joe Biden works out lifting weights and exercising on a Peloton bike machine. Any more about health? No, nothing. Maybe in the debate tonight, Trump and Biden will ask each other about cognition and health. Maybe. But don’t count on it.
