I don’t think it’s particularly useful to follow the details of Trump’s ear in tedious detail. (Gun violence is bad, even if it was just a scratch.)
I do think it’s useful to remember — and to relentlessly point out evidence — that Trump is a congenital liar, a con man, and a ham who manipulates the press and people’s emotions.
It’s also useful to decry his break with the long-standing norm of the public receiving accurate medical information about candidates.
